NFSv4: try lease recovery on NFS4ERR_EXPIRED
Currently, if an nfs server returns NFS4ERR_EXPIRED to open(), we return EIO to applications without even trying to recover. Fixes: 272289a3df72 ("NFSv4: nfs4_do_handle_exception() handle revoke/expiry of a single stateid") Signed-off-by: Robert Milkowski <rmilkowski@gmail.com> Reviewed-by: Trond Myklebust <trond.myklebust@hammerspace.com> Signed-off-by: Anna Schumaker <Anna.Schumaker@Netapp.com>
