Subject: [PATCH md-6.12 28/41] md/md-bitmap: mrege md_bitmap_cond_end_sync() into bitmap_operations
From: Yu Kuai <yukuai3@...wei.com>
So that the implementation won't be exposed, and it'll be possible
to invent a new bitmap by replacing bitmap_operations.
Also change the parameter from bitmap to mddev, to avoid access
bitmap outside md-bitmap.c as much as possible.
