Subject: [PATCH 00/16] rcu/nocb updates
Date: Thu, 28 Jan 2021 18:12:06 +0100 [thread overview]
Message-ID: <20210128171222.131380-1-frederic@kernel.org> (raw)
So this set has grown further than I expected.
This addresses most reviews from Paul and also consolidates the nocb
timers code.
Please mind the very first patch that is a stable bugfix.

rcu/dev
HEAD: 75991420c246c26f598602da1a70947b5bdf77b6
Thanks,
Frederic
