[PATCHv5 01/16] VFS: introduce helpers for the s_dirt flag

From: Artem Bityutskiy
Date: Sun Jun 06 2010 - 10:56:50 EST

From: Artem Bityutskiy <Artem.Bityutskiy@xxxxxxxxx>

This patch introduces 3 new VFS helpers: 'sb_mark_dirty()',
'sb_mark_clean()', and 'sb_is_dirty()'. The helpers simply
change or test the 'sb->s_dirt' flag. The plan is to make
every FS use these helpers instead of manipulating the
'sb->s_dirt' flag directly.

This patch also switches VFS and all FSes to use the new helpers.
It just mechanically changes:
sb->s_dirt = 1 to sb_mark_dirty(sb)
sb->s_dirt = 0 to sb_mark_clean(sb)
if (sb->s_dirt) to if (sb_is_dirty(sb))

This patch does not introduce any functional changes, just wraps
the 's_dirt'.
