From 19c9c466e5c79402cbf8929f922011b02fbb59bd Mon Sep 17 00:00:00 2001 From: Jaegeuk Kim Date: Wed, 10 Sep 2014 15:04:03 -0700 Subject: [PATCH] f2fs: do not skip latest inode information In f2fs_sync_file, if there is no written appended writes, it skips to write its node blocks. But, if there is up-to-date inode page, we should write it to update its metadata during the roll-forward recovery.
