RDMA/rtrs-srv: Add event tracing support 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.
