Subject: [PATCH 1,2/4 v3] slub: use __cmpxchg_double_slab() at interrupt disabled place
Date: Fri, 18 May 2012 02:03:39 +0900 [thread overview]
Message-ID: <1337274219-5279-1-git-send-email-js1304@gmail.com> (raw)
In-Reply-To: <alpine.DEB.2.00.1205171149050.8534@router.home>
get_freelist(), unfreeze_partials() are only called with interrupt disabled,
so __cmpxchg_double_slab() is suitable.
