From 6233caa9d5b153c2190d6c1c35c1dd1010104fc1 Mon Sep 17 00:00:00 2001 From: Jiro SEKIBA Date: Thu, 23 Jul 2009 01:26:33 +0900 Subject: nilfs2: fix disorder of nilfs_write_super in nilfs_sync_fs This fixes disorder of nilfs_write_super in nilfs_sync_fs. Commiting super block must be the end of the function so that every changes are reflected. ->sync_fs() is not called frequently so this makes nilfs_sync_fs call nilfs_commit_super instead of nilfs_write_super.
