Subject: [PATCH RESEND v2 02/10] blk: Introduce ->corrupted_range() for block device
Date: Fri, 29 Jan 2021 14:27:49 +0800	[thread overview]
Message-ID: <20210129062757.1594130-3-ruansy.fnst@cn.fujitsu.com> (raw)
In-Reply-To: <20210129062757.1594130-1-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.
