Subject: [PATCH 0/2] sched: Introduce rcuwait
Date: Thu, 22 Dec 2016 09:01:34 -0800
Message-ID: <1482426096-12792-1-git-send-email-dave@stgolabs.net> (raw)

Hi,

Here's an updated version of the pcpu rwsem writer wait/wake changes
with the abstractions wanted by Oleg. Patch 1 adds rcuwait (for a lack
of better name), and patch 2 trivially makes use of it. 

Has survived torture testing, which is actually very handy in this case
particularly dealing with equal amount of reader and writer threads.

Thanks.
