Subject[PATCH AUTOSEL 4.19 141/219] f2fs: fix block address for __check_sit_bitmap
Date
From: Qiuyang Sun <sunqiuyang@huawei.com>

[ Upstream commit 9249dded7b5cb539a8c8698b25d08a3c15261470 ]

Should use lstart (logical start address) instead of start (in dev) here.
This fixes a bug in multi-device scenarios.
