Subject: hfs: remove extra mdb write on unmount
X-Git-Url: http://drtracing.org/?a=commitdiff_plain;h=a3742d4828caeffab4cb075b562a4ed92d3e74d6;p=deliverable%2Flinux.git

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.
