Subject: [PATCH] f2fs: fix block address for __check_sit_bitmap
Date: Tue, 18 Dec 2018 17:32:23 +0800 [thread overview]
Message-ID: <20181218093223.25242-1-sunqiuyang@huawei.com> (raw)
From: Qiuyang Sun <sunqiuyang@huawei.com>
Should use lstart (logical start address) instead of start (in dev) here.
This fixes a bug in multi-device scenarios.
