    Subject[PATCH AUTOSEL 5.5 532/542] NFSv4: try lease recovery on NFS4ERR_EXPIRED
    Date
    From: Robert Milkowski <rmilkowski@gmail.com>

    [ Upstream commit 924491f2e476f7234d722b24171a4daff61bbe13 ]

    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")
