Subject: [PATCH -v4 0/8] locking/mutex: Rewrite basic mutex
Date: Fri, 07 Oct 2016 16:52:43 +0200 [thread overview]
Message-ID: <20161007145243.361481786@infradead.org> (raw)
Hi all,
Since you all should not be sending patches during the merge window, I figured
I should to keep you all occupied with something.
Please review, test and otherwise try to break these here patches.
I would like to get these patches into -tip (and -next) once the merge window
closes, so please spend these quiet days staring at this stuff.
Small changes only, mostly the handoff logic as suggested by Waiman last time.
