get_thread_area.2 is a system call.
Other manpages seems to differentiate functions (i.e. (g)lib(c) functions)
and system calls. This make it more consistent.

As noted by Andrey:
The purpose of the assert macro, defined in <assert.h>,
is to provide a tool to check for programming mistakes
or program logic errors. However, the assert macro must
never be used to perform checks for run time errors,
since, with the NDEBUG macro defined, expressions within
the assert macro invocations are not evaluated/checked
for, resulting in behavior that was not originally intended.
...
The pages affected in the core package are
execve(2)
pipe(2)
tee(2)
fmemopen(3)
mq_notify(3)
qsort(3)

Starting with Linux 2.6.30, the MS_RELATIME behavior became
the default, and MS_STRICTATIME is required to obtain the
traditional semantics.

Some bit rot had crept in regarding the discussion of the
number of arguments in older versions of this syscall.
Simplify the text to just say that Linux 2.4 and earlier
didn't have ptid, tls, and ctid arguments.

As reported by Motohiro:
"man poll" describe this error code.
>ERRORS
> EBADF An invalid file descriptor was given in one of the sets.
but current kernel implementation ignore invalid file descriptor,
not return EBADF.
...
In the other hand, SUSv3 talk about
> POLLNVAL
> The specified fd value is invalid. This flag is only valid in the
> revents member; it shall ignored in the events member.
and
> If the value of fd is less than 0, events shall be ignored, and
> ireevents shall be set to 0 in that entry on return from poll().
but, no desribe EBADF.
(see http://www.opengroup.org/onlinepubs/009695399/functions/poll.html)
So, I think the implementation is correct.
Why don't we remove EBADF description?

It was noted on lkml that the fork behaviour is documented
for the POSIX AIO calls, but not for the Linux native calls.
Here is a patch which adds a small blurb that folks will
hopefully find useful.
Upon fork(), the child process does not inherit the
io_context_t data structures returned by io_setup,
and thus cannot submit further asynchronous I/O or
reap event completions for said contexts.

These operations use the 'data' argument as a signal number,
like PTRACE_CONT.
