Subject: [PATCH 0/2] resurrect
Date: Sat, 20 Feb 2021 17:21:34 +0000 [thread overview]
Message-ID: <cover.1613841429.git.asml.silence@gmail.com> (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.
