[PATCH 7/8] NFSv4.1: Don't call nfs4_schedule_state_recovery() unnecessarily

[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index]

 



Currently, nfs4_handle_exception() will call it twice if called with an
error of -NFS4ERR_STALE_CLIENTID, -NFS4ERR_STALE_STATEID or
-NFS4ERR_EXPIRED.
