Subject[PATCH v3 2/4] fat: introduce mark_fsinfo_dirty helper
Date
From: Artem Bityutskiy <artem.bityutskiy@linux.intel.com>

This is a preparation patch which introduces a 'mark_fsinfo_dirty()'
helper function which just sets the 's_dirt' flag to 1 so far. I'll add more
code to this helper later, so I do not mark it as 'inline'.
