[LTP] [PATCH v2 0/2] epoll_pwait2() timeout regression test

[Martin Doucha]

There seems to be a regression in kernel v6.14 where epoll_pwait2()
interprets very small timeout values (~1000ns) as infinity and waits
for events forever. This patchset adds regression test for this bug
and a necessary refactor for do_epoll_pwait() to allow high precision
timeouts.

Martin Doucha (2):
  epoll_pwait: Refactor timeout to struct timespec
  Add regression test for epoll_pwait2() timeout
