Tracepoints can start with digits, although we don't have many of these:
$ rg -g '*.h' '\bTRACE_EVENT\([0-9]' net/mac802154/trace.h 53:TRACE_EVENT(802154_drv_return_int, ...
net/ieee802154/trace.h 66:TRACE_EVENT(802154_rdev_add_virtual_intf, ...
include/trace/events/9p.h 124:TRACE_EVENT(9p_client_req, ...
Just allow names to start with digits too so e.g. perf probe -e '9p:*' works
