Subject: md/raid1: remove unnecessary BUG_ON
X-Git-Url: http://drtracing.org/?a=commitdiff_plain;h=b3c95b425e0991840262dba8dd095f2682dbf848;p=deliverable%2Flinux.git

md/raid1: remove unnecessary BUG_ON

Since bitmap_start_sync will not return until
sync_blocks is not less than PAGE_SIZE>>9, so
the BUG_ON is not needed anymore.
