Subject: [PATCH v3 03/11] fs: Introduce ->corrupted_range() for superblock
Date: Mon, 8 Feb 2021 18:55:22 +0800	[thread overview]
Message-ID: <20210208105530.3072869-4-ruansy.fnst@cn.fujitsu.com> (raw)
In-Reply-To: <20210208105530.3072869-1-ruansy.fnst@cn.fujitsu.com>

Memory failure occurs in fsdax mode will finally be handled in
filesystem.  We introduce this interface to find out files or metadata
affected by the corrupted range, and try to recover the corrupted data
if possiable.
