From: John Harrison <John.C.Harrison@xxxxxxxxx> The scheduler needs to be informed of each batch buffer completion. This is done via the user interrupt mechanism. The epilogue of each batch buffer submission updates a sequence number value (seqno) and triggers a user interrupt. This change hooks the scheduler in to the processing of that interrupt via the notify_ring() function. The scheduler also has clean up code that needs to be done outside of the interrupt context, thus notify_ring() now also pokes the scheduler's work queue.
