Subject: [PATCH 4/9] f2fs: allocate new segment aligned with sections
Date: Mon, 01 Apr 2013 15:55:55 +0900	[thread overview]
Message-ID: <1364799360-23145-4-git-send-email-jaegeuk.kim@samsung.com> (raw)
In-Reply-To: <1364799360-23145-1-git-send-email-jaegeuk.kim@samsung.com>

When allocating a new segment under the LFS mode, we should keep the section
boundary.
