Subject: [PATCH] cleanup comment in include/linux/compaction.h for defer_compaction
Date: Thu, 24 Nov 2011 10:57:54 +0800	[thread overview]
Message-ID: <4ECDB2B2.2000206@gmail.com> (raw)

No compact_defer_limit is found in kernel source code.
Per the code implementation, compact_defer_limit should be
zone->compact_defer_shift. Cleanup the comment.
