From a3742d4828caeffab4cb075b562a4ed92d3e74d6 Mon Sep 17 00:00:00 2001 From: Artem Bityutskiy Date: Thu, 12 Jul 2012 17:28:46 +0300 Subject: [PATCH] hfs: remove extra mdb write on unmount HFS calls 'hfs_write_super()' from 'hfs_put_super()' in order to write the MDB to the media. However, it is not needed because VFS calls '->sync_fs()' before calling '->put_super()' - so by the time we are in 'hfs_write_super()', the MDB is already synchronized.
