fs: dlm: requestqueue busy wait to event based wait
This patch changes the requestqueue busy waiting algorithm to use atomic counter values and wait_event() to wait until the requestqueue is empty. It will slightly reduce the number of holding ls_requestqueue_mutex mutex. Signed-off-by: Alexander Aring <aahringo@redhat.com> Signed-off-by: David Teigland <teigland@redhat.com>
