Subject: [PATCH v2 17/15] slab: replace non-existing 'struct freelist *' with 'void *'
Date: Wed, 30 Oct 2013 19:04:01 +0900 [thread overview]
Message-ID: <1383127441-30563-2-git-send-email-iamjoonsoo.kim@lge.com> (raw)
In-Reply-To: <1383127441-30563-1-git-send-email-iamjoonsoo.kim@lge.com>
There is no 'strcut freelist', but codes use pointer to 'struct freelist'.
Although compiler doesn't complain anything about this wrong usage and
codes work fine, but fixing it is better.
