Subject: NFSv4.2: LAYOUTSTATS may return NFS4ERR_ADMIN/DELEG_REVOKED
X-Git-Url: http://git.cdn.openwrt.org/?a=commitdiff_plain;h=206b3bb57481758b5fe98e90f47abb0f3fc0954e;p=openwrt%2Fstaging%2Fblogic.git

NFSv4.2: LAYOUTSTATS may return NFS4ERR_ADMIN/DELEG_REVOKED

We should handle those errors in the same way we handle the other
stateid errors: by invalidating the faulty layout stateid.
