epoll_create.2
Rework discussion of 'size' argument
Add .SS for description of epoll_create1()
epoll_wait.2
Another thread can add to epoll instance while epoll_wait is blocked
See https://bugzilla.kernel.org/show_bug.cgi?id=43072
Clarify that epoll_pwait() blocks calling *thread*
A few wording improvements
fchmodat.2
Note difference between glibc wrapper and underlying system call
The wrapper function has a 'flags' argument (which currently
serves no purpose), while the underlying system call does not.
fcntl.2
Explain behaviour of F_GETLEASE during lease break
Change type of arg from "long" to "int"
Various fcntl(2) commands require an integral 'arg'.
The man page said it must be "long" in all such cases.
However, for the cases covered by POSIX, there is an
explicit requirement that these arguments be "int".
