Subject: [PATCH v3 0/2] add epoll_pwait2 syscall
Date: Wed, 18 Nov 2020 09:46:14 -0500 [thread overview]
Message-ID: <20201118144617.986860-1-willemdebruijn.kernel@gmail.com> (raw)
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
