From 37ae5a0f5287a52cf51242e76ccf198d02ffe495 Mon Sep 17 00:00:00 2001 From: Tetsuo Handa Date: Sat, 18 Dec 2021 18:41:56 +0900 Subject: block: use "unsigned long" for blk_validate_block_size(). 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.
