Merge branch 'for-mingo' of git://git.kernel.org/pub/scm/linux/kernel/git/paulmck/linux-rcu into core/rcu
- Updates to the handling of expedited grace periods, perhaps most notably parallelizing their initialization. Other changes include fixes from Boqun Feng. - Miscellaneous fixes. These include an nvme fix from Nitzan Carmi that I am carrying because it depends on a new SRCU function cleanup_srcu_struct_quiesced(). This branch also includes fixes from Byungchul Park and Yury Norov. - Updates to reduce lock contention in the rcu_node combining tree. These are in preparation for the consolidation of RCU-bh, RCU-preempt, and RCU-sched into a single flavor, which was requested by Linus Torvalds in response to a security flaw whose root cause included confusion between the multiple flavors of RCU. - Torture-test updates that save their users some time and effort. Conflicts: drivers/nvme/host/core.c Signed-off-by: Ingo Molnar <mingo@kernel.org>
