[PATCH -v3 00/10] locking/mutex: Rewrite basic mutex
From: Peter Zijlstra
Date: Mon Sep 05 2016 - 08:45:50 EST
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.
