Changes to individual pages
---------------------------

clone.2
    Michael Kerrisk
        Add kernel versions for various CLONE_* constants
    Michael Kerrisk
        CLONE_NEWIPC governs mechanisms that don't have filesystem pathnames
    Michael Kerrisk
        CLONE_NEWIPC doesn't mount the POSIX MQ file system
    Michael Kerrisk
        Add an example program (CLONE_NEWUTS)
    Michael Kerrisk
        Some reworking of CLONE_NEWIPC text
            No substantial content changes.
    Michael Kerrisk
        SEE ALSO: add kcmp(2)
        SEE ALSO: add setns(2)

fallocate.2
    Michael Kerrisk
        FALLOC_FL_* flags are defined in glibc only since 2.18

getxattr.2
removexattr.2
setxattr.2
    Michael Kerrisk  [Andrew Perepechko, ]
        Note that ENOATTR is a synonym for ENODATA
            Various people have pointed out that strace(1) shows ENODATA
            for the case where the named attribute does not exist, or
            the process has no access to this attribute. ENODATA
            and ENOATTR are in fact defined as synonyms. Point this out
            in the man page, so that people understand the strace(1) info.

            See https://bugzilla.kernel.org/show_bug.cgi?id=51871

getxattr.2
listxattr.2
removexattr.2
setxattr.2
    Michael Kerrisk
        Put errors under ERRORS section
            The errno values on these pages were listed in a nonstandard
            way under the RETURN VALUE section. Put them in ERRORS sections.

init_module.2
    Michael Kerrisk  [Rusty Russell]
        ERRORS: Add errors for module signatures (EBADMSG, ENOKEY)

link.2
mkdir.2
mknod.2
open.2
rename.2
symlink.2
write.2
mkfifo.3
    Mark Hills
        Document EDQUOT error
            The return error EDQUOT is not documented in open(2), write(2),
            symlink(2) etc.

            Whether inodes or disk blocks are required for each function
            is something I based on received wisdom and BSD documentation,
            rather than tracing the code to the kernel. For symlink(2)
            this certainly depends on the file system type.

listxattr.2
    Michael Kerrisk  [Theodore Ts'o]
        Fix RETURN VALUE description
            On success, 0 may be returned, so change wording from
            "positive number" to "nonnegative number".

outb.2
    Michael Kerrisk
        Add SYNOPSIS

prctl.2
    Kees Cook
        Document PR_SET_PTRACER
            Document the Yama LSM's prctl handler that allows processes to
            declare ptrace restriction exception relationships via
            PR_SET_PTRACER.
    Michael Kerrisk
        Make it explicit that PR_SET_PTRACER replaces previous setting
            The attribute is a scalar, not a list.
    Shawn Landden
        Document EINVAL error for PR_SET_PTRACER
    Michael Kerrisk
        Document PR_GET_TID_ADDRESS

ptrace.2
    Michael Kerrisk
        Document PTRACE_O_EXITKILL
    Michael Kerrisk
        Place PTRACE_SETOPTIONS list in alphabetical order

query_module.2
    Michael Kerrisk
        Must be called using syscall(2)
            Yes, the call is way obsolete, but add this info
            for completeness.

recvmmsg.2
    Elie De Brauwer
        Add/correct kernel version info for recvmmsg() and MSG_WAITFORNONE
            This patch isolates the since/version related fixes as requested.
            This change introduces the following delta:
             * The page states it was added in 2.6.32 but it is only added
                2.6.33 (ref: http://kernelnewbies.org/Linux_2_6_33)
             * The MSG_WAITFORONE flag was in turn only added in 2.6.34
               (ref: http://kernelnewbies.org/Linux_2_6_34)
    Elie De Brauwer
        Add an example program

        Note feature test macro requirements for 'siginfo_t'
            See https://bugzilla.kernel.org/show_bug.cgi?id=52931

syscalls.2
    Michael Kerrisk
        Add kern_features(2)
    Michael Kerrisk
        Add utrap_install(2)
            Sparc-specific, present since ancient times
    Michael Kerrisk
        Add finit_module(2)

sysctl.2
    Michael Kerrisk  [Garrett Cooper]
        ERRORS: EACCES as a synonym for EPRM
            See https://bugzilla.kernel.org/show_bug.cgi?id=46731
            and http://thread.gmane.org/gmane.linux.ltp/11413/focus=957635

        Remove crufty text about 'time_t' on "other systems"
            Back in 2006, some text came in via Debian patches that seems
            crufty. Remove it.

getaddrinfo.3

core.5
proc.5
    Kees Cook
        Clarify suid_dumpable versus core_pattern
            In Linux 3.6, additional requirements were placed on core_pattern
            when suid_dumpable is set to 2. Document this and include commit
            references.
    Justin Lebar
        statm's "shared" field refers to pages backed by files
            I noticed that statm's "shared" field doesn't match the sum of
            all the "shared" entries in smaps [1].

            The kernel docs explain that statm's "shared" field is "number of
            pages that are shared (i.e. backed by a file)" [2].  smaps appears
            to call a page shared if it's mapped by at least two processes,
            which explains this discrepancy.

            I'm not a kernel hacker, but it appears to me they do mean "i.e."
            and not "e.g." in the statm description: In
            fs/proc/task_mmu.c::task_statm, I see

                *shared = get_mm_counter(mm, MM_FILEPAGES);

            Here's a patch which updates the man page to match the (hopefully
            correct) kernel docs.

        Put /proc/sys/kernel/hotplug in alphabetical order

            Info taken from commit ce0e7b28fb75cb003cfc8d0238613aaf1c55e797
    Michael Kerrisk  [Peter Lekeynstein]
        Document /prod/[pid]/oom_score_adj
            Text taken directly from Documentation/filesystems/proc.txt,
            with some light editing.
