Subject: [PATCH 0/3] locking/rwsem: __rwsem_mark_wake() improvements
Date: Fri, 5 Aug 2016 01:04:42 -0700 [thread overview]
Message-ID: <1470384285-32163-1-git-send-email-dave@stgolabs.net> (raw)
Hi,
Wanpeng recently reminded me of how horrible this function is, and we
are now in a position to improve it; see patch 3 for details.
Please consider for v4.9.
Thanks!
Davidlohr Bueso (3):
locking/rwsem: Return void in __rwsem_mark_wake()
locking/rwsem: Remove a few useless comments
locking/rwsem: Scan the wait_list for readers only once
