Subject: [PATCH] atomic.h : x86_64 atomic64_add_return
Date: Thu, 21 Dec 2006 14:42:08 -0500 [thread overview]
Message-ID: <20061221194208.GA25249@Krystal> (raw)
In-Reply-To: <20061221001405.GO28643@Krystal>
atomic64_add_return fix for volatile removal
atomic64_add_return should follow the change done to atomic.h following the
removal of "volatile" in the atomic_t type, just like atomic_add_return.
It applies cleanly on top of my "atomic.h : x86_64" patch posted in this
thread.
