+Subject: SUNRPC: Avoid RPC delays when exiting suspend
+
+From: Trond Myklebust <trond.myklebust@hammerspace.com>
+
+commit 66eb3add452aa1be65ad536da99fac4b8f620b74 upstream.
+
+Jon Hunter: "I have been tracking down another suspend/NFS related
+issue where again I am seeing random delays exiting suspend. The delays
+can be up to a couple minutes in the worst case and this is causing a
+suspend test we have to fail."
+
+Change the use of a deferrable work to a standard delayed one.
+
+Reported-by: Jon Hunter <jonathanh@nvidia.com>
+Tested-by: Jon Hunter <jonathanh@nvidia.com>
+Fixes: 7e0a0e38fcfea ("SUNRPC: Replace the queue timer with a delayed work function")
