Subject: [PATCH v2 2/7] affs: remove useless superblock writeout on unmount

From: Artem Bityutskiy <artem.bityutskiy@...ux.intel.com>

We do not need to write out the superblock from '->put_super()' because VFS has
already called '->sync_fs()' by this time and the superblock has already been
written out. Thus, remove the 'affs_commit_super()' infocation from
'affs_put_super()'.
