From 5887d291d792773368f6eaf1759aad109bcd78eb Mon Sep 17 00:00:00 2001 From: Jaegeuk Kim Date: Tue, 8 Oct 2013 09:30:33 +0900 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.
