Subject: [PATCH 5.4 64/65] dm zoned: assign max_io_len correctly
From: Hou Tao <houtao1@...wei.com>
commit 7b2377486767503d47265e4d487a63c651f6b55d upstream.
The unit of max_io_len is sector instead of byte (spotted through
code review), so fix it.
Fixes: 3b1a94c88b79 ("dm zoned: drive-managed zoned block device target")
