Alexander Aring 1815d9bf02 fs: dlm: interrupt posix locks only when process is killed 
[ Upstream commit 59e45c758ca1b9893ac923dd63536da946ac333b ]

If a posix lock request is waiting for a result from user space
(dlm_controld), do not let it be interrupted unless the process
is killed. This reverts commit a6b1533e9a57 ("dlm: make posix locks
interruptible"). The problem with the interruptible change is
that all locks were cleared on any signal interrupt. If a signal
was received that did not terminate the process, the process
could continue running after all its dlm posix locks had been
cleared. A future patch will add cancelation to allow proper
interruption.
