[PATCH 1/2] AFFS: clean up dirty flag usage

From: Artem Bityutskiy
Date: Fri Jun 11 2010 - 11:09:32 EST


From: Artem Bityutskiy <Artem.Bityutskiy@xxxxxxxxx>

In 'affs_write_super()': remove ancient and wrong commented code,
remove unneeded 'clean' variable, so the function becomes a bit
cleaner and simpler.

In 'affs_remount(): remove unnecessary SB dirty flag changes.
