Message-ID: <20211013134154.1085649-1-yanfei.xu@windriver.com> (raw)
[patch1] locking:remove rcu_read_lock/unlock as we already disabled preemption
v1->2: also remove the unnecessary rcu_read_lock/unlock in rwsem
[patch2] locking/rwsem: disable preemption for spinning region
[patch3] locking/rwsem: fix comments about reader optimistic lock stealing conditions
These two patches were sent to mailing list some weeks ago, but it seemed
to be missed, so send them again.
