From 2291059c852706c6f5ffb400366042b7625066cd Mon Sep 17 00:00:00 2001 From: Pranith Kumar Date: Tue, 23 Sep 2014 10:29:50 -0400 Subject: locking,arch: Use ACCESS_ONCE() instead of cast to volatile in atomic_read() Use the much more reader friendly ACCESS_ONCE() instead of the cast to volatile. This is purely a stylistic change.
