From: Alexander Lobakin <aleksander.lobakin@xxxxxxxxx>
commit 4ca532d64648d4776d15512caed3efea05ca7195 upstream.
bitmap_set_bits() does not start with the FS' prefix and may collide
with a new generic helper one day. It operates with the FS-specific
types, so there's no change those two could do the same thing.
Just add the prefix to exclude such possible conflict.
