commit df4e7ac0bb70abc97fbfd9ef09671fc084b3f9db upstream. ext2_quota_write() doesn't properly setup bh it passes to ext2_get_block() and thus we hit assertion BUG_ON(maxblocks == 0) in ext2_get_blocks() (or we could actually ask for mapping arbitrary number of blocks depending on whatever value was on stack). Fix ext2_quota_write() to properly fill in number of blocks to map.
