Interesting problem.

Say you do a VFS_SYNC. Is there a way to distinguish blocks written to
accomplish the VFS_SYNC from the blocks written afterward? I mean, is
there any notion of a block's "generation," where VFS_SYNC's mark the
beginning of a new generation? Having that info (I realize it might be
a tall order for that info!), this is not too complicated, right?
