| |
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.
