+---------------------------
+
+fcntl.2
+ Michael Kerrisk
+ Note that glibc 2.11 papers over the kernel F_GETOWN bug

+
+mlock.2
+ Michael Kerrisk

+
+poll.2
+ Michael Kerrisk
+ Fix discussion of ppoll() timeout argument
+ 1. Rename ppoll)(_ argument to "timeout_ts" to distinguish it
+ from the poll() argument in the text.
+ 2. More accurately describe the poll() call that is equivalent
+ to ppoll().
+
+posix_fadvise.2
+ Michael Kerrisk
+ Add sync_file_range(2) under SEE ALSO
+
+prctl.2
+ Michael Kerrisk
+ Correct PR_SET_KEEPCAPS description
+ The "keep capabilities" flag only affects the treatment of
+ permitted capabilities, not effective capabilities.
+ Also: other improvements to make the PR_SET_KEEPCAPS text clearer.
+
+select_tut.2

+ Fix bug in example program
+
+sigaction.2
+ Michael Kerrisk
+ Add TRAP_BRANCH and TRAP_HWBKPT to si_code values for SIGTRAP
+ Michael Kerrisk

+ Michael Kerrisk
+ Document f_frsize field.

+ Note effect of iCONFIG_MEMORY_FAILURE on MAX_SWAPFILES
+ From 2.6.32, MAX_SWAPFILES is decreased by 1 if the kernel is
+ built with CONFIG_MEMORY_FAILURE.
+
+syscalls.2
+ Michael Kerrisk
+ Bring system call list up to date with Linux 2.6.33
+ Michael Kerrisk
+ Fix kernel version number for utimes()
+
+cproj.3
+ Michael Kerrisk
+ Note fix for C99 conformance in glibc 2.12.
+
+crypt.3
+ Petr Baudis
+ Correct note on key portion significance
+ As Marcel Moreaux notes:
+
+ The Linux manpage for crypt()[1] contains the following
+ statement as the last sentence of the NOTES section:
+
+ In the SHA implementation the entire key is significant
+ (instead of only the first 8 bytes in MD5).
+
+ It should probably say "DES" where it says "MD5" (and maybe
+ "MD5/SHA" where it says "SHA"), because in MD5 password hashing,
+ the entire key is significant, not just the first 8 bytes.
+
+ This patch fixes the wording.
+
+fmemopen.3
+ Michael Kerrisk
+ Bug fix in example program
+
+ftw.3
+ Michael Kerrisk
+ Note that if 'fn' changes CWD, the results are undefined
+ Michael Kerrisk
+ Clarify description of fpath argument
+ As reported by Pierre Habouzit, 'fpath' is not relative
+ to 'dirpath'. It is either relative to the calling process's
+ current working directory (if 'dirpath' was relative), or it
+ is absolute (if 'dirpath' was absolute).
+
+getaddrinfo.3
+ Christian Franke
+ Fix a field name mixup: s/ai_family/ai_flags/
+
+getline.3
+ Robert Wohlrab
+ Remove unneeded check before free()
+ The manpage of getline shows an example with an extra NULL pointer
+ check before it calls free. This is unneeded according to free(3):
+
+ If ptr is NULL, no operation is performed.
+
+ This patch removes the "if" check.
+
+ See http://bugs.debian.org/cgi-bin/bugreport.cgi?bug=572508
+
+log.3
+log10.3
+log2.3
+ Jan Engelhardt
+ Add cross-references to other-base logarithmic functions
+
+opendir.3
+ Petr Baudis
+ Specify feature test macro requirements for fdopendir(3)
+ Currently, there is no note on the fact that fdopendir() is
+ POSIX.2008-only.
+
+openpty.3
+ Eric Blake
+ Use const as appropriate
+ Michael Kerrisk
+ Note glibc version that added "const" to function arguments
+ Michael Kerrisk
+ Explicitly note that these functions are not in POSIX
+
+resolver.3
+ Michael Kerrisk
+ Fix declaration of dn_comp() in SYNOPSIS
+ Remove the second 'exp_dn' from the calling signature.
+
+termios.3
+ Michael Kerrisk
+ Change NOFLSH text to speak of characters, not signals
+
+core.5
+ Michael Kerrisk
+ Update description of coredump_filter
+ Kernel 2.6.24 added MMF_DUMP_ELF_HEADERS.
+ Kernel 2.6.28 added MMF_DUMP_HUGETLB_PRIVATE and
+ MMF_DUMP_HUGETLB_SHARED.
+
+elf.5
+ Daisuke HATAYAMA
+ Document PN_XNUM extension
+ In linux-2.6.34-rc1, an ELF core extension was added; user-land
+ tools manipulating ELF core dump such as gdb and binutils has
+ already been modified before; so elf.5 needs to be modified
+ accordingly.
+
+ You can follow information on the ELF extension via the LKML post:
+ http://lkml.org/lkml/2010/1/3/103
+ Date Mon, 04 Jan 2010 10:06:07 +0900 (JST)
+ Subject ... elf coredump: Add extended numbering support
+
+ This Linux-specific extension was added in kernel 2.6.34.
+
+ Reviewed-by: Petr Baudis <pasky@suse.cz>
+
+ Michael Kerrisk
+ Remove EI_BRAND
+ As reported by Yuri Kozlov and confirmed by Mike Frysinger,
+ EI_BRAND is not in GABI
+ (http://www.sco.com/developers/gabi/latest/ch4.eheader.html)
+ It looks to be a BSDism
+ Michael Kerrisk
+ Remove words under '.note': "described below"
+ The existing text is broken, because there is
+ no '"Note Section" format' describe below. Simplest
+ solution is to remove the words "described below".
+
+filesystems.5
+ Jeff Barry
+ Add discussion of ntfs and ext4
+
+proc.5
+ Michael Kerrisk
+ Simplify description of /proc/sys and /proc/sys/fs
+ In the description of these directories, there's no need
+ to list all the files and subdirectories that they contain;
+ that information is provided by the entries that follow.
+
+services.5
+ Yuri Kozlov
+ Remove crufty reference to nonexistent BUGS section
+
+capabilities.7
+ Michael Kerrisk
+ Document CAP_SYS_RESOURCE and F_SETPIPE_SZ
+ With CAP_SYS_RESOURCE, a process can increase pipe capacity above
+ /proc/sys/ps/pipe-max-size.
+ Michael Kerrisk
+ Add get_robust_list() info under CAP_SYS_PTRACE
+ Michael Kerrisk
+ Add MADV_HWPOISON under CAP_SYS_ADMIN
+
+signal.7
+ Michael Kerrisk
+ Make a clearer statement about nonportable aspect of signal(2)
+ Make a clearer statement that signal(2) is less portable for
+ establishing a signal handler.
+
+socket.7
+ Michael Kerrisk
+ Use consistent language to describe read-only socket options
+
+udp.7
+ Michael Kerrisk
+ Add FIONREAD warning.
+ Warn that FIONREAD can't can't distinguish case of a zero-length
+ datagram from the case where no datagrams are available.
