Subject[PATCH v3 0/2] add epoll_pwait2 syscall
Date
From: Willem de Bruijn <willemb@google.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
