    Subject[PATCH 5.3 048/105] SUNRPC: Avoid RPC delays when exiting suspend
    Date
    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.
