  "message": "ext4: Wait for proper transaction commit on fsync\n\nWe cannot rely on buffer dirty bits during fsync because pdflush can come\nbefore fsync is called and clear dirty bits without forcing a transaction\ncommit. What we do is that we track which transaction has last changed\nthe inode and which transaction last changed allocation and force it to\ndisk on fsync.\n\nSigned-off-by: Jan Kara \u003cjack@suse.cz\u003e\nSigned-off-by: \"Theodore Ts\u0027o\" \u003ctytso@mit.edu\u003e\n",
