block/rnbd: introduce rnbd_access_modes

2023-06-12T01:48:42+00:00

Add one new array (marked with __maybe_unused to prevent gcc warning about "defined but not used" with W=1), then we can remove rnbd_access_mode_str and rnbd-common.c accordingly.

block/rnbd-srv: Add event tracing support

2022-08-22T13:52:51+00:00

Add event tracing mechanism for following routines: - create_sess() - destroy_sess() - process_rdma() - process_msg_sess_info() - process_msg_open() - process_msg_close() How to use: 1. Load the rnbd_server module 2. cd /sys/kernel/debug/tracing 3. If all the events need to be enabled: echo 1 > events/rnbd_srv/enable 4. OR only speific routine/event needs to be enabled e.g. echo 1 > events/rnbd_srv/create_sess/enable 5. cat trace 5. Run some workload which can trigger create_sess() routine/event Signed-off-by: Santosh Pradhan Signed-off-by: Jack Wang Signed-off-by: Md Haris Iqbal Link: https://lore.kernel.org/r/20220818105551.110490-2-haris.iqbal@ionos.com Signed-off-by: Jens Axboe
