[PATCH 1/1] Make bm_blocks to match previous semantic

[jgq516@gmail.com]

From: Guoqing Jiang <gqjiang@suse.com>

The bm_blocks is modified by commit fe60ce (md/bitmap: use
sector_div for sector_t divisions), but it makes bm_blocks
has different value which is changed from like "a/b" to "a%b",
need to correct this to make sure cluster-md still works.
