From eae7bf13993ea919b319991d4491cffe45c4054d Mon Sep 17 00:00:00 2001 From: Hou Tao Date: Mon, 15 Jun 2020 11:33:23 +0800 Subject: dm zoned: assign max_io_len correctly commit 7b2377486767503d47265e4d487a63c651f6b55d upstream. The unit of max_io_len is sector instead of byte (spotted through code review), so fix it.
