[PATCH 18/18] DO NOT SUBMIT: directory rename stuff for redo_after_renames
From: Elijah Newren <newren@gmail.com>
I believe the
ci->dirmask & sidemask
stuff was leftovers from before I added dirs_removed. I think it's
dead, useless code; just need to check.
Also, the
!mi || mi->clean
portions should only be triggerable once I do the redo_after_renames
stuff.
