==================== Changes in man-pages-5.10 ====================


Newly documented interfaces in existing pages
---------------------------------------------

access.2
    Michael Kerrisk
        Document faccessat2()
            faccessat2() was added in Linux 5.8 and enables a fix to
            longstanding bugs in the faccessat() wrapper function.

membarrier.2
    Peter Oskolkov  [Alejandro Colomar]
        Update for Linux 5.10
            Linux kernel commit 2a36ab717e8fe678d98f81c14a0b124712719840
            (part of 5.10 release) changed sys_membarrier prototype/parameters
            and added two new commands [MEMBARRIER_CMD_PRIVATE_EXPEDITED_RSEQ
            and MEMBARRIER_CMD_REGISTER_PRIVATE_EXPEDITED_RSEQ].

mount.2
statfs.2
    Ross Zwisler
        Add NOSYMFOLLOW flags to mount(2) and statfs(2)


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

cacheflush.2
    Alejandro Colomar
        Document Architecture-specific variants
    Alejandro Colomar  [Heinrich Schuchardt]
        Document __builtin___clear_cache() as a more portable alternative

clone.2
sigaltstack.2
    Michael Kerrisk
        clone(CLONE_VM) disables the alternate signal stack

mmap.2
    Michael Kerrisk
        Clarify SIGBUS text and treatment of partial page at end of a mapping

perf_event_open.2
    Namhyung Kim  [Alejandro Colomar]
        Update man page with recent kernel changes

sigaltstack.2
    Michael Kerrisk
        Clarify that the alternate signal stack is per-thread

timer_getoverrun.2
    Michael Kerrisk
        timer_getoverrun() now clamps the overrun count to DELAYTIMER_MAX
            See https://bugzilla.kernel.org/show_bug.cgi?id=12665.

uselib.2
posix_memalign.3
profil.3
rtime.3
    Michael Kerrisk
        Remove some text about libc/libc5
            With this change, there remain almost no vestiges of information
            about the long defunct Linux libc.

signal.7
    Michael Kerrisk  [Heinrich Schuchardt, Dave Martin]
        Add some details on the execution of signal handlers
            Add a "big picture" of what happens when a signal handler
            is invoked.

tcp.7
    Alejandro Colomar  [Philip Rowlands]
        tcp_syncookies: It is now an integer [0, 2]
            Since Linux kernel 3.12, tcp_syncookies can have the value 2,
            which sends out cookies unconditionally.
