The patch titled
md/bitmap: fix online removal of file-backed bitmaps
has been added to the -mm tree. Its filename is
md-bitmap-fix-online-removal-of-file-backed-bitmaps.patch
See http://www.zip.com.au/~akpm/linux/patches/stuff/added-to-mm.txt to find
out what to do about this
From: NeilBrown <neilb@xxxxxxx>
When "mdadm --grow /dev/mdX --bitmap=none" is used to remove a filebacked
bitmap, the bitmap was disconnected from the array, but the file wasn't closed
(until the array was stopped).
The file also wasn't closed if adding the bitmap file failed.
