Hi hackers,
Hi hackers,
v3 is v2 rebased over current master (5f14f82280d); cfbot flagged the
set as needing a rebase after typedefs.list drifted. No code changes.
Regards,
Dmitry Fomin
Dmitry Fomin (7):
wait_event_timing: add --enable-wait-event-timing flag and
wait_event_capture GUC
wait_event_timing: record per-backend wait event statistics (stats
level)
wait_event_timing: expose overflow counters and add reset functions
ci: build one task with --enable-wait-event-timing
wait_event_timing: allocate the per-backend array lazily in DSA
wait_event_timing: add trace level with a per-session ring buffer
wait_event_timing: add query-attribution markers to the trace ring
