Subject: [PATCH -v3 00/10] locking/mutex: Rewrite basic mutex
Date: Mon, 05 Sep 2016 14:36:36 +0200 [thread overview]
Message-ID: <20160905123636.450529224@infradead.org> (raw)
Hi,
New version, with improved Changelogs and bits. This version has survived aim7
loads on my 2 socket machine, I've yet to try the 4 socket. But over-all it
seem to behave as expected.
That is, all except the last patch, which I just wrote and hasn't even seen a
compiler up close.
