Add event tracing mechanism for following routines:
- send_io_resp_imm()
How to use:
1. Load the rtrs_server module
2. cd /sys/kernel/debug/tracing
3. If all the events need to be enabled:
echo 1 > events/rtrs_srv/enable
4. OR only speific routine/event needs to be enabled e.g.
echo 1 > events/rtrs_srv/send_io_resp_imm/enable
5. cat trace
6. Run some I/O workload which can trigger send_io_resp_imm()
