commit 5f3a7ebc358fdcbafcab4f1bf4067120fb519dfc
Author: Adhemerval Zanella <adhemerval.zanella@linaro.org>
Date: Wed Jan 12 11:31:53 2022 -0300
Linux: Add epoll_pwait2 (BZ #27359)
It is similar to epoll_wait, with the difference the timeout has
nanosecond resoluting by using struct timespec instead of int.
Although Linux interface only provides 64 bit time_t support, old
32 bit interface is also provided (so keep in sync with current
practice and to no force opt-in on 64 bit time_t).
Checked on x86_64-linux-gnu and i686-linux-gnu.
