Subject: [PATCH] slub: change cmpxchg_double_slab in get_freelist() to __cmpxchg_double_slab
Date: Fri, 11 May 2012 00:56:18 +0900 [thread overview]
Message-ID: <1336665378-2967-1-git-send-email-js1304@gmail.com> (raw)
get_freelist() is only called by __slab_alloc with interrupt disabled,
so __cmpxchg_double_slab is suitable.
