The patch titled
md/bitmap: remove dead code from md/bitmap
has been removed from the -mm tree. Its filename is
md-bitmap-remove-dead-code-from-md-bitmap.patch
This patch was dropped because it was merged into mainline or a subsystem tree
------------------------------------------------------
Subject: md/bitmap: remove dead code from md/bitmap
From: NeilBrown <neilb@xxxxxxx>
bitmap_active is never called, and the BITMAP_ACTIVE flag is never users or
tested, so discard them both.
Also remove some out-of-date 'todo' comments.
