Subject: [RFC PATCH v3 3/9] fs: Introduce ->corrupted_range() for superblock
Date: Tue, 15 Dec 2020 20:14:08 +0800	[thread overview]
Message-ID: <20201215121414.253660-4-ruansy.fnst@cn.fujitsu.com> (raw)
In-Reply-To: <20201215121414.253660-1-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.
