   API NOTES
     All the "aio_*" calls are more or less thin wrappers around the syscall
     with the same name (sans "aio_"). The arguments are similar or
     identical, and they all accept an additional (and optional) $callback
            IO::AIO::mmap $data, -s $fh, IO::AIO::PROT_READ, IO::AIO::MAP_SHARED, $fh;
            aio_mlock $data; # mlock in background
     aio_mlockall $flags, $callback->($status)
         Calls the "mlockall" function with the given $flags (a combination
-        of "IO::AIO::MCL_CURRENT" and "IO::AIO::MCL_FUTURE").
+        of "IO::AIO::MCL_CURRENT", "IO::AIO::MCL_FUTURE" and
+        "IO::AIO::MCL_ONFAULT").
         On systems that do not implement "mlockall", this function returns
-        -1 and sets errno to "ENOSYS".
+        -1 and sets errno to "ENOSYS". Similarly, flag combinations not
+        supported by the system result in a return value of -1 with errno
+        being set to "EINVAL".
         Note that the corresponding "munlockall" is synchronous and is
         documented under "MISCELLANEOUS FUNCTIONS".
         Example: asynchronously lock all current and future pages into
         below, for full accuracy.
         File birth time is only available when the OS and perl support it
         (on FreeBSD and NetBSD at the time of this writing, although support
         is adaptive, so if your OS/perl gains support, IO::AIO can take
-        avdantage of it). On systems where it isn't available, 0 is
+        advantage of it). On systems where it isn't available, 0 is
         currently returned, but this might change to "undef" in a future
         version.
     ($atime, $mtime, $ctime, $btime, ...) = IO::AIO::st_xtime
         Returns access, modification, change and birth time all in one go,
     ($atime, $mtime, $ctime, $btime, ...) = IO::AIO::st_xtimensec
         Like the functions above, but returns all four times in one go (and
         maybe more in future versions).
     $counter = IO::AIO::st_gen
-        Returns the generation counter of the file. This is only available
+        Returns the generation counter (in practice this is just a random
-        on platforms which have this member in their "struct stat" (most
+        number) of the file. This is only available on platforms which have
-        BSDs at the time of this writing) and generally only to the root
+        this member in their "struct stat" (most BSDs at the time of this
-        usert. If unsupported, 0 is returned, but this might change to
+        writing) and generally only to the root usert. If unsupported, 0 is
-        "undef" in a future version.
+        returned, but this might change to "undef" in a future version.
     Example: print the high resolution modification time of /etc, using
     "stat", and "IO::AIO::aio_stat".
        if (stat "/etc") {
         version.
         On systems where this call is not supported or is not emulated, this
         call returns falls and sets $! to "ENOSYS".
+    IO::AIO::mlockall $flags
+        Calls the "eio_mlockall_sync" function, which is like
+        "aio_mlockall", but is blocking.
     IO::AIO::munlock $scalar, $offset = 0, $length = undef
         Calls the "munlock" function, undoing the effects of a previous
         "aio_mlock" call (see its description for details).
     IO::AIO::munlockall
         Example: create a pipe race-free w.r.t. threads and fork:
            my ($rfh, $wfh) = IO::AIO::pipe2 IO::AIO::O_CLOEXEC
               or die "pipe2: $!\n";
+    $fh = IO::AIO::memfd_create $pathname[, $flags]
+        This is a direct interface to the Linux memfd_create(2) system call.
+        The (unhelpful) default for $flags is 0, but your default should be
+        "IO::AIO::MFD_CLOEXEC".
+        On success, the new memfd filehandle is returned, otherwise returns
+        "undef". If the memfd_create syscall is missing, fails with
+        "ENOSYS".
+        Please refer to memfd_create(2) for more info on this call.
+        The following $flags values are available: "IO::AIO::MFD_CLOEXEC",
+        "IO::AIO::MFD_ALLOW_SEALING" and "IO::AIO::MFD_HUGETLB".
+        Example: create a new memfd.
+           my $fh = IO::AIO::memfd_create "somenameforprocfd", IO::AIO::MFD_CLOEXEC
+              or die "m,emfd_create: $!\n";
-    $fh = IO::AIO::eventfd [$initval, [$flags]]
+        =item $fh = IO::AIO::eventfd [$initval, [$flags]]
         This is a direct interface to the Linux eventfd(2) system call. The
         (unhelpful) defaults for $initval and $flags are 0 for both.
         On success, the new eventfd filehandle is returned, otherwise
         returns "undef". If the eventfd syscall is missing, fails with
         "IO::AIO::EFD_CLOEXEC", "IO::AIO::EFD_NONBLOCK" and
         "IO::AIO::EFD_SEMAPHORE" (Linux 2.6.30).
         Example: create a new eventfd filehandle:
-           $fh = IO::AIO::eventfd 0, IO::AIO::O_CLOEXEC
+           $fh = IO::AIO::eventfd 0, IO::AIO::EFD_CLOEXEC
               or die "eventfd: $!\n";
     $fh = IO::AIO::timerfd_create $clockid[, $flags]
         This is a direct interface to the Linux timerfd_create(2) system
-        call. The (unhelpful) default for $flags is 0.
+        call. The (unhelpful) default for $flags is 0, but your default
+        should be "IO::AIO::TFD_CLOEXEC".
         On success, the new timerfd filehandle is returned, otherwise
-        returns "undef". If the eventfd syscall is missing, fails with

-        "ENOSYS".
+        with "ENOSYS".
         Please refer to timerfd_create(2) for more info on this call.
         The following $clockid values are available:
         "IO::AIO::CLOCK_REALTIME", "IO::AIO::CLOCK_MONOTONIC"
