+
+New and rewritten pages
+-----------------------
+
+close_range.2
+    Stephen Kitt, Michael Kerrisk  [Christian Brauner]
+        New page documenting close_range(2)
+
+process_madvise.2
+    Suren Baghdasaryan, Minchan Kim  [Michal Hocko, Alejandro Colomar,
+    Michael Kerrisk]
+        Document process_madvise(2)
+
+fileno.3
+    Michael Kerrisk
+        Split fileno(3) content out of ferror(3) into new page
+            fileno(3) differs from the other functions in various ways.
+            For example, it is governed by different standards,
+            and can set 'errno'. Conversely, the other functions
+            are about examining the status of a stream, while
+            fileno(3) simply obtains the underlying file descriptor.
+            Furthermore, splitting this function out allows
+            for some cleaner upcoming changes in ferror(3).

+Global changes
+--------------
+
+Various pages
+    Alejandro Colomar
+        SYNOPSIS: Use 'restrict' in prototypes
+            This change has been completed for *all* relevant pages
+            (around 135 pages in total).
+
+Various pages
+    Alejandro Colomar  [Zack Weinberg]
+        Remove unused <sys/types.h>
+            The manual pages are already inconsistent in which headers need
+            to be included.  Right now, not all of the types used by a
+            function have their required header included in the SYNOPSIS.
+
+            If we were to add the headers required by all of the types used by
+            functions, the SYNOPSIS would grow too much.  Not only it would
+            grow too much, but the information there would be less precise.
+
+            Having system_data_types(7) document each type with all the
+            information about required includes is much more precise, and the
+            info is centralized so that it's much easier to maintain.
+
+            So let's document only the include required for the function
+            prototype, and also the ones required for the macros needed to
+            call the function.
+
+            <sys/types.h> only defines types, not functions or constants, so
+            it doesn't belong to man[23] (function) pages at all.
+
+            I ignore if some old systems had headers that required you to
+            include <sys/types.h> *before* them (incomplete headers), but if
+            so, those implementations would be broken, and those headers
+            should probably provide some kind of warning.  I hope this is not
+            the case.
+
+            [mtk: Already in 2001, POSIX.1 removed the requirement to
+            include <sys/types.h> for many APIs, so this patch seems
+            well past due.]
+
+A few pages
+    Alejandro Colomar
+        Add notes about missing glibc wrappers
+
+_exit.2
+abort.3
+err.3
+exit.3
+pthread_exit.3
+setjmp.3
+    Alejandro Colomar
+        SYNOPSIS: Use 'noreturn' in prototypes
+            Use standard C11 'noreturn' in these manual page for
+            functions that do not return.
+
+Various pages
+    Ganimedes Colomar  [Alejandro Colomar]
+        Normalize SYNOPSIS notes about nonexistent glibc wrappers
+            To easily distinguish documentation about glibc wrappers from
+            documentation about kernel syscalls, let's have a normalized
+            'Note' in the SYNOPSIS, and a further explanation in the page body
+            (NOTES in most of them), as already happened in many (but not all)
+            of the manual pages for syscalls without a wrapper.  Furthermore,
+            let's normalize the messages, following membarrier.2 (because it's
+            already quite extended), so that it's easy to use grep to find
+            those pages.
+        Normalize NOTES about nonexistent glibc wrappers
+            This commit normalizes texts under sections other than SYNOPSIS
+            (most of them in NOTES).
+
+
+Global changes (formatting fixes and minor edits)
+-------------------------------------------------
+
+Various pages
+    Michael Kerrisk
+        ERRORS: remove redundant statement that 'errno' is set
+            This is implied in every other manual page. There is no need to
+            state it explicitly in these pages.
+
+Various pages
+    Michael Kerrisk
+        Use periods more consistently inside code comments
+            In general, complete sentences in free-standing comments
+            should be terminated by periods.
+
+A few pages
+    Michael Kerrisk
+        Better table formatting
+            In particular, allow for rendering in widths different from
+            (especially less than) 80 columns.
+
+Various pages
+    Michael Kerrisk
+        Consistency fix-up in FTMs
+            Generally, place '||' at start of a line, rather than the end of
+            the previous line.
+
+            Rationale: this placement clearly indicates that that each piece
+            is an alternative.
+
+Various pages
+    Michael Kerrisk  [Alejandro Colomar]
+        Bring more whitespace consistency in SYNOPSIS
+            The use of vertical white space in the SYNOPSIS sections
+            is rather inconsistent. Make it more consistent, subject to the
+            following heuristics:
+
+            * Prefer no blank lines between function signatures by default.
+            * Where many functions are defined in the SYNOPSIS, add blank
+              lines where needed to improve readability, possibly by using
+              blank lines to separate logical groups of functions.
+
+Various pages
+    Alejandro Colomar
+       Consistently use 'unsigned int'
+            Most pages use 'unsigned int' (and the kernel too).
+            Make them all do so.
+
+Various pages
+    Michael Kerrisk
+        Various improvements in wording in RETURN VALUE
+
+Various pages
+    Michael Kerrisk
+        s/Glibc versions </Glibc </ in Feature Test Macro discussions
+            Use a more compact notation that will render less wide
+            on the terminal.
+
+Various pages
+    Michael Kerrisk
+        Standardize wording around setting of 'errno' on error
+            In the RETURN VALUE sections, a number of different wordings
+            are used in to describe the fact that 'errno' is set on error.
+            There's no reason for the difference in wordings, since the same
+            thing is being described in each case. Switch to a standard
+            wording that is the same as FreeBSD and similar to the wording
+            used in POSIX.1.
+
+            In this change, "to indicate the cause of the error"
+            is changed to "to indicate the error".
+
+Various pages
+    Michael Kerrisk
+        Add missing .nf/.fi in FTM info
+
+Various pages
+    Michael Kerrisk
+        Simplify mark-up for Feature Test Macro requirements
+            Different source styles are used in different pages to achieve the
+            same formatted output, and in some cases the source mark-up is a
+            rather convoluted combination of .RS/.RE/.TP/.PD macros. Simplify
+            this greatly, and unify all of the pages to use more or less the
+            same source code style. This makes the source code rather easier
+            to read, and may simplify future scripted global changes.
+
+            The feature test macro info is currently bracketed by .nf/.fi
+            pairs. This is not strictly necessary (i.e., it makes no
+            difference to the rendered output), but for the moment we keep
+            these "brackets" in case they may be replaced with something else.
+
+Various pages
+    Michael Kerrisk
+        Use real minus signs in pathnames
+
+Various pages
+    Michael Kerrisk
+        Standardize wording around setting of 'errno' on error
+            In the RETURN VALUE sections, a number of different wordings
+            are used in to describe the fact that 'errno' is set on error.
+            There's no reason for the difference in wordings, since the same
+            thing is being described in each case. Switch to a standard
+            wording that is the same as FreeBSD and similar to the wording
+            used in POSIX.1.
+
+            In this change, reword various cases saying that 'errno' is set
+            "appropriately" to "is set to indicate the error".
+
+Various pages
+    Michael Kerrisk
+        Improve formatting in ATTRIBUTES
+            Make the formatting more consistent inside the tables in the
+            ATTRIBUTES sections. Make the source code more uniform; in
+            particular, eliminate the use of custom tweaks using
+            'lbwNN'/'lwNN' and .br macros.  In addition, ensure that
+            hyphenation and text justification do not occur inside the tables.
+
+Various pages
+    Michael Kerrisk
+      Use .nf/.fi in SYNOPSIS
+            The majority of pages use .nf/.fi in SYNOPSIS, but there are
+            still many that don't and use .br to achieve newlines. Fix many
+            of those. This brings greater consistency to the pages, which
+            eases editing and may ease future scripted edits to the pages.
+
+Various pages
+    Michael Kerrisk
+        Standardize wording around setting of 'errno' on error
+            In the RETURN VALUE sections, a number of different wordings
+            are used in to describe the fact that 'errno' is set on error.
+            There's no reason for the difference in wordings, since the same
+            thing is being described in each case. Switch to a standard
+            wording that is the same as FreeBSD and similar to the wording
+            used in POSIX.1.
+
+            In this change, miscellaneous descriptions of the setting
+            of 'errno' are reworded to the norm of "is set to indicate
+            the error".
+
+Various pages
+    Michael Kerrisk
+        Use "\-" to generate real minus in circumstances where appropriate
+            Use \- for math formulas, pathnames, manual page cross references,
+            etc.
+
+Various pages
+    Michael Kerrisk
+        Inside code blocks (.EX/.EE) use \- to get real minus signs
+            A real minus can be cut and pasted...
+
+Various pages
+    Alejandro Colomar
+        Remove explicit blank lines, replacing them with .PP when appropriate
+
+Various pages
+    Michael Kerrisk
+        Use internally consistent continuation indents in SYNOPSIS
+            In the SYNOPSIS, a long function prototype may need to be
+            continued over to the next line. The continuation line is
+            indented according to the following rules:
+
+            1. If there is a single such prototype that needs to be continued,
+               then align the continuation line so that when the page is
+               rendered on a fixed-width font device (e.g., on an xterm) the
+               continuation line starts just below the start of the argument
+               list in the line above.  (Exception: the indentation may be
+               adjusted if necessary to prevent a very long continuation line
+               or a further continuation line where the function prototype is
+               very long.)
+
+               Thus:
+
+                   int tcsetattr(int fd, int optional_actions,
+                                 const struct termios *termios_p);
+
+            2. But, where multiple functions in the SYNOPSIS require
+               continuation lines, and the function names have different
+               lengths, then align all continuation lines to start in the
+               same column.  This provides a nicer rendering in PDF output
+               (because the SYNOPSIS uses a variable width font where
+               spaces render narrower than most characters).
+
+               Thus:
+
+                   int getopt(int argc, char * const argv[],
+                              const char *optstring);
+                   int getopt_long(int argc, char * const argv[],
+                              const char *optstring,
+                              const struct option *longopts, int *longindex);
+
+Various pages
+    Michael Kerrisk
+        Standardize wording around setting of 'errno' on error
+            In the RETURN VALUE sections, a number of different wordings
+            are used in to describe the fact that 'errno' is set on error.
+            There's no reason for the difference in wordings, since the same
+            thing is being described in each case. Switch to a standard
+            wording that is the same as FreeBSD and similar to the wording
+            used in POSIX.1.
+
+            In this change, fix some instances stating that 'errno' is set
+            "appropriately" to instead say "to indicate the error".

+
+Changes to individual pages
+---------------------------
+
+alloc_hugepages.2
+    Michael Kerrisk
+        CONFORMING TO: reword to reflect that these system calls are long gone
+
+cacheflush.2
+    Alejandro Colomar
+        Update SYNOPSIS for glibc wrapper
+            Glibc uses 'void *' instead of 'char *'.
+            And the prototype is declared in <sys/cachectl.h>.
+
+clone.2
+    Valentin Kettner
+        Fix types in clone_args
+            A file descriptor is an int so it should be stored through an int
+            pointer while parent_tid should have the same type as child_tid
+            which is pid_t pointer.
+
+close.2
+    Michael Kerrisk
+        SEE ALSO: add close_range(2)
+
+copy_file_range.2
+    Alejandro Colomar
+        Document glibc wrapper instead of kernel syscall
+            Glibc uses 'off64_t' instead of 'loff_t'.
+
+delete_module.2
+    Alejandro Colomar
+        SYNOPSIS: Fix prototype parameter types
+            The Linux kernel uses 'unsigned int' instead of 'int' for the
+            'flags' parameter.  As glibc provides no wrapper, use the same
+            type the kernel uses.
+
+epoll_create.2
+    Michael Kerrisk
+        CONFORMING TO: mention that epoll_create1() is Linux-specific
+
+epoll_wait.2
+    Michael Kerrisk
+        CONFORMING TO: mention that epoll_pwait() is Linux-specific
+
+execve.2
+    Palmer Dabbelt
+        Correct the versions of Linux that don't have ARG_MAX argv/envp size
+
+execveat.2
+    Alejandro Colomar
+        Fix prototype
+            It's been 6 years since execveat(2) was added to the kernel,
+            and there's still no glibc wrapper.  Let's document the kernel
+            syscall prototype.
+
+getcpu.2
+    Michael Kerrisk  [Alejandro Colomar]
+        Rewrite page to describe glibc wrapper function
+            Since glibc 2.29, there is a wrapper for getcpu(2).
+            The wrapper has only 2 arguments, omitting the unused
+            third system call argument. Rework the manual page
+            to reflect this.
+
+getgid.2
+getuid.2
+    Michael Kerrisk
+        Note that these interfaces never modify 'errno'
+            See https://www.austingroupbugs.net/view.php?id=511
+            and the POSIX.1-2008 specifications of the interfaces.
+
+gethostname.2
+    Michael Kerrisk
+        Update FTM requirements for gethostname()
+
+getpagesize.2
+getdtablesize.3
+    Michael Kerrisk
+        Update/correct FTM requirements
+
+getrusage.2
+    Michael Kerrisk
+        Starting in 2.33, glibc no longer provides vtimes()
+
+ioctl_tty.2
+    Michael Kerrisk
+        Reformat argument type information
+            The current mark-up renders poorly. To resolve this, move
+            the type information into a separate line.
+
+ipc.2
+    Alejandro Colomar
+        Fix prototype parameter types
+
+kcmp.2
+    Michael Kerrisk
+        Since Linux 5.12, kcmp() availability is unconditional
+            kcmp() is no longer dependent on CONFIG_CHECKPOINT_RESTORE.
+
+keyctl.2
+    Alejandro Colomar
+        SYNOPSIS: Fix prototype parameter types
+            The Linux kernel uses 'unsigned long'.
+            There's no reason to use the typedef '__kernel_ulong_t'.
+
+lookup_dcookie.2
+    Alejandro Colomar
+        Use standard types: u64 -> uint64_t
+
+madvise.2
+    Michael Kerrisk
+        SEE ALSO: add process_madvise(2)
+
+mlock.2
+    Alejandro Colomar
+        mlock2(): Fix prototype parameter types
+            The documented prototype for mlock2() was a mix of the
+            glibc wrapper prototype and the kernel syscall prototype.
+            Let's document the glibc wrapper prototype, which is shown below.
+    Michael Kerrisk
+        CONFORMING TO: note more explicitly which APIs are in the standards
+
+mmap2.2
+    Alejandro Colomar
+        Fix prototype parameter types
+            There are many slightly different prototypes for this syscall,
+            but none of them is like the documented one.
+            Of all the different prototypes,
+            let's document the asm-generic one.
+
+mount.2
+    Michael Kerrisk
+        Note that the 'data' argument can be NULL
+
+move_pages.2
+    Alejandro Colomar
+        Add notes about missing glibc wrappers
+
+open.2
+rename.2
+    Alyssa Ross
+        Refer to tmpfs rather than shmem
+            If I'm understanding correctly, tmpfs is a filesystem built on
+            shmem, so I think it's more correct (and probably much more
+            widely understandable) to refer to tmpfs here.
+
+pciconfig_read.2
+    Alejandro Colomar
+        SYNOPSIS: Fix prototype parameter types
+            Use the glibc prototypes instead of the kernel ones.
+            Exception: use 'int' instead of 'enum'.
+
+pidfd_open.2
+    Michael Kerrisk
+        Note the process_madvise(2) use case for PID file descriptors
+
+readlink.2
+    Michael Kerrisk  [Jonny Grant]
+        Emphasize that the returned buffer is not null-terminated
+
+s390_pci_mmio_write.2
+    Alejandro Colomar
+        SYNOPSIS: Add 'const' qualifier
+            s390_pci_mmio_write() uses 'const void *' instead of 'void *'.
+

+    Alejandro Colomar
+        Add note about missing glibc wrappers
+

+        Add note about missing glibc wrapper
+
+splice.2
+    Alejandro Colomar
+        Use 'off64_t' instead of 'loff_t'
+            The kernel syscall uses 'loff_t', but the glibc wrapper uses 'off64_t'.
+            Let's document the wrapper prototype, as in other pages.
+
+spu_create.2
+    Alejandro Colomar
+        SYNOPSIS: Fix prototype parameter type
+            The 'flags' parameter of spu_create() uses 'unsigned int'.
+
+spu_run.2
+    Alejandro Colomar
+        SYNOPSIS: Fix prototype parameter types
+            The 2nd and 3rd parameters of spu_run() use 'uint32_t *'.
+
+stat.2
+    Jonathan Wakely  [Alejandro Colomar]
+        Remove <unistd.h> from SYNOPSIS
+            There seems to be no reason <unistd.h> is shown here, so remove it.
+    Michael Kerrisk
+        Move the obsolete _BSD_SOURCE FTM to the end of the FTM info
+
+syscall.2
+    Peter H. Froehlich
+        Update superh syscall convention

+
+tkill.2
+    Alejandro Colomar
+        SYNOPSIS: Fix prototype parameter types
+            All but the last parameters of t[g]kill() use 'pid_t',
+            both in the kernel and glibc.
+
+vmsplice.2
+    Alejandro Colomar
+        SYNOPSIS: Fix prototype parameter type
+            The 3rd parameter of vmsplice() uses 'size_t' in glibc.

+        Remove fileno(3) content that was migrated to new fileno(3) page
+    Michael Kerrisk
+        Add a RETURN VALUE section
+    Michael Kerrisk
+        POSIX.1-2008: these functions won't change 'errno' if 'stream' is valid
+            See https://www.austingroupbugs.net/view.php?id=401.
+
+fread.3
+    Alessandro Bono
+        EXAMPLES: swap size and nmemb params
+            It works both ways, but this one feels more right. We are reading
+            four elements sizeof(*buffer) bytes each.
+
+fseeko.3
+    Michael Kerrisk
+        Move info about obsolete FTM from SYNOPSIS to NOTES

+unlockpt.3
+    Michael Kerrisk
+        Remove mention of _XOPEN_SOURCE_EXTENDED FTM
+            This rather ancient FTM is not mentioned in other pages for
+            reasons discussed in feature_test_macros(7).  Remove this FTM
+            from the three pages where it does appear.
