Message-id: <1381192395-30296-1-git-send-email-jaegeuk.kim@samsung.com> Date: Tue, 08 Oct 2013 09:33:15 +0900 From: Jaegeuk Kim <jaegeuk.kim@...sung.com> To: unlisted-recipients:; (no To-header on input) Cc: Jaegeuk Kim <jaegeuk.kim@...sung.com>, linux-fsdevel@...r.kernel.org, linux-kernel@...r.kernel.org, linux-f2fs-devel@...ts.sourceforge.net Subject: [PATCH] f2fs: avoid unnecessary checkpoints During the f2fs_put_super procedure, we don't need to conduct checkpoint all the time, since we don't need to do that if superblock is clean.
