From 93be0950070b5bcb22600cb1cbb62f93c058a5dd Mon Sep 17 00:00:00 2001 From: Andres Freund Date: Thu, 8 Jan 2015 13:08:05 +0100 Subject: [PATCH] Move comment about sun cc's __machine_rw_barrier being a full barrier. I'd accidentally written the comment besides the read barrier, instead of the full barrier, implementation.
