Subject: [PATCH 0/2] resurrect
Date: Sat, 20 Feb 2021 17:21:34 +0000	[thread overview]
Message-ID: <[email protected]> (raw)

Combined approach with tryget, fallbacking to trying completion and
doing synchronize_rcu, where the last one is very unlikely to happen
and limited by one such per register syscall.

I expect 1/2 to cleanly apply for stable, 2/2 needs to be backported
by hand.

  io_uring: wait potential ->release() on resurrect
  io_uring: wait for ->release() on rsrc resurrect
