From: Linus Torvalds Date: Wed, 6 Dec 2006 22:42:57 +0000 (-0800) Subject: x86[-64]:Remove 'volatile' from atomic_t X-Git-Tag: v2.6.20-rc1~34^2~20^2~28 X-Git-Url: http://pilppa.com/gitweb/?a=commitdiff_plain;h=f9e9dcb38f5106fa8cdac04a9e967d5487f1cd20;p=linux-2.6-omap-h63xx.git x86[-64]:Remove 'volatile' from atomic_t Any code that relies on the volatile would be a bug waiting to happen anyway. Don't encourage people to think that putting 'volatile' on data structures somehow fixes problems. We should always use proper locking (and other serialization) techniques.
