Subject: [PATCH v2 1/1] NFS4.1 handle interrupted slot reuse from ERR_DELAY
Date: Wed, 26 Apr 2017 14:21:22 -0400	[thread overview]
Message-ID: <20170426182122.1301-1-kolga@netapp.com> (raw)

If the RPC slot was interrupted and server replied to the next
operation on the "reused" slot with ERR_DELAY, don't clear out
the "interrupted" flag until we properly recover.
