FWIW, XFS has over 200 trace events now, and we still haven't converted
the btree tracing to use the TRACE_EVENT() infrastructure (which has
roughly 100 trace points and 10-15 unique trace events per btree type in
I also just posted a patch that adds about 15 new trace events to log
recovery (I added them to track down a bug in some new code), so the
number of trace events in XFS is still growing and will continue to grow
for some time....
