Subject: [PATCH 01/16] mm/slab: fix stale code comment
Date: Thu, 14 Jan 2016 14:24:14 +0900 [thread overview]
Message-ID: <1452749069-15334-2-git-send-email-iamjoonsoo.kim@lge.com> (raw)
In-Reply-To: <1452749069-15334-1-git-send-email-iamjoonsoo.kim@lge.com>
We use freelist_idx_t type for free object management whose size
would be smaller than size of unsigned int. Fix it.
