Subject: [PATCH tip/core/rcu 0/5] Callback-overload update for v5.7
Date: Fri, 14 Feb 2020 16:18:16 -0800 [thread overview]
Message-ID: <20200215001816.GA15284@paulmck-ThinkPad-P72> (raw)
Hello!
This series contains updates to handling of callback-overload condiitons.
1. Clear ->core_needs_qs at GP end or self-reported QS.
2. React to callback overload by aggressively seeking quiescent
states.
3. React to callback overload by boosting RCU readers.
4. Fix spelling mistake "leval" -> "level".
5. Update __call_rcu() comments.
Thanx, Paul
