Subject[PATCH v1 5/9] VFS: remove unused superblock helpers
Date
From: Artem Bityutskiy <artem.bityutskiy@linux.intel.com>

Remove the 'sb_mark_dirty()', 'sb_mark_clean()' and 'sb_is_dirty()' helpers
which are not used. I introduced them 2 years and the intention was to make
all file-systems use them in order to be able to optimize 'sync_supers()'.
However, Al Viro vetoed my patches at the end and asked me to push superblock
management down to file-systems and get rid of the 's_dirt' flag completely,
as well as kill 'sync_supers()' altogether. Thus, remove the helpers.
