Subject: [PATCH tip/core/rcu 0/4] RCU-sync updates for v5.3
Date: Thu, 30 May 2019 08:08:16 -0700	[thread overview]
Message-ID: <20190530150816.GA32130@linux.ibm.com> (raw)

Hello!

This series contains flavor-consolidation updates to RCU-sync:

1.	Kill rcu_sync_type/gp_type, courtesy of Oleg Nesterov.

2.	Use DEFINE_STATIC_PERCPU_RWSEM() to initialize dup_mmap_sem in
	uprobes, courtesy of Oleg Nesterov.

3.	Add DEFINE_PERCPU_RWSEM(), use it to initialize
	cgroup_threadgroup_rwsem in percpu-rwsem, courtesy of Oleg Nesterov.

4.	Simplify the state machine, courtesy of Oleg Nesterov.

							Thanx, Paul
