+Subject: block: use "unsigned long" for blk_validate_block_size().
+
+From: Tetsuo Handa <penguin-kernel@i-love.sakura.ne.jp>
+
+commit 37ae5a0f5287a52cf51242e76ccf198d02ffe495 upstream.
+
+Since lo_simple_ioctl(LOOP_SET_BLOCK_SIZE) and ioctl(NBD_SET_BLKSIZE) pass
+user-controlled "unsigned long arg" to blk_validate_block_size(),
+"unsigned long" should be used for validation.
