RTNL is required for sending notifications and if rtnl can not be acquired, current code skips sending notification. This is especially bad if the monitoring values selected are large. This patch adds a bitmask and uses a bit per such work-queue and attempts to reschedule the work (aggressively) until notifications are sent out and then resumes the regular cycle.
