Subject: [RFC PATCH v3 2/9] blk: Introduce ->corrupted_range() for block device
Date: Tue, 15 Dec 2020 20:14:07 +0800	[thread overview]
Message-ID: <20201215121414.253660-3-ruansy.fnst@cn.fujitsu.com> (raw)
In-Reply-To: <20201215121414.253660-1-ruansy.fnst@cn.fujitsu.com>

In fsdax mode, the memory failure happens on block device.  So, it is
needed to introduce an interface for block devices.  Each kind of block
device can handle the memory failure in ther own ways.
