Subject: [PATCH tip/core/rcu 0/5] Pre-gp_seq miscellaneous fixes for v4.19
Date: Mon, 25 Jun 2018 16:04:10 -0700 [thread overview]
Message-ID: <20180625230410.GA13250@linux.vnet.ibm.com> (raw)
Hello!
The following miscellaneous fixes come before the infamous ->gp_seq
conversion:
1. Add debugging info to the assertion detecting tasks queued on
the ->blkd_tasks list at unexpected times.
2. Use the proper lockdep annotation in dump_blkd_tasks(), courtesy
of Boqun Feng.
3. Exclude near-simultaneous RCU CPU stall warnings, thus reducing
the probability of interleaved (and thus inscrutable) warnings.
4. Add diagnostics for failure to respond to a request for a new
grace period.
5. Make rcu_gp_cleanup() write only once to ->gp_flags.
Thanx, Paul
