Subject: [PATCH 02/15] NFS: Revalidate the file mapping on all fatal writeback errors
Date: Mon, 6 Jan 2020 15:25:01 -0500 [thread overview]
Message-ID: <20200106202514.785483-3-trond.myklebust@hammerspace.com> (raw)
In-Reply-To: <20200106202514.785483-2-trond.myklebust@hammerspace.com>
If a write or commit failed, and the mapping sees a fatal error, we
need to revalidate the contents of that mapping.
Fixes: 06c9fdf3b9f1 ("NFS: On fatal writeback errors, we need to call nfs_inode_remove_request()")
