Subject: [PATCH v3 0/2] add epoll_pwait2 syscall
From: Willem de Bruijn <willemb@...gle.com>
Enable nanosecond timeouts for epoll.
Analogous to pselect and ppoll, introduce an epoll_wait syscall
variant that takes a struct timespec instead of int timeout.
See patch 1 for more details.
patch 1: new syscall
patch 2: selftest
Willem de Bruijn (2):
epoll: add nsec timeout support with epoll_pwait2
selftests/filesystems: expand epoll with epoll_pwait2
