       ioscheduler.elv_completed_request
              Fires when a request is completed

               See probe::ioscheduler.elv_completed_request(3stap)
               for details.

       ioscheduler.elv_add_request.kp
              kprobe based probe to indicate that a request was added to the request queue

               See probe::ioscheduler.elv_add_request.kp(3stap)
               for details.

       ioscheduler.elv_add_request.tp
              tracepoint based probe to indicate a request is added to the request queue.

               See probe::ioscheduler.elv_add_request.tp(3stap)

       ioscheduler.elv_add_request
              probe to indicate request is added to the request queue.

               See probe::ioscheduler.elv_add_request(3stap)
               for details.

       ioscheduler_trace.elv_completed_request
              Fires when a request is

               See probe::ioscheduler_trace.elv_completed_request(3stap)

       ioscheduler_trace.elv_issue_request
              Fires when a request is

               See probe::ioscheduler_trace.elv_issue_request(3stap)
               for details.

       ioscheduler_trace.elv_requeue_request
              Fires when a request is

               See probe::ioscheduler_trace.elv_requeue_request(3stap)
               for details.

       ioscheduler_trace.elv_abort_request
              Fires when a request is aborted.

               See probe::ioscheduler_trace.elv_abort_request(3stap)
               for details.

       ioscheduler_trace.plug
              Fires when a request queue is plugged;

               See probe::ioscheduler_trace.plug(3stap)
               for details.

       ioscheduler_trace.unplug_io
              Fires when a request queue is unplugged;

               See probe::ioscheduler_trace.unplug_io(3stap)
               for details.

       ioscheduler_trace.unplug_timer
