perf parse: Allow tracepoint names to start with digits
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 trace -e '9p:*'" works Reviewed-by: Ian Rogers <irogers@google.com> Signed-off-by: Dominique Martinet <asmadeus@codewreck.org> Tested-by: Ian Rogers <irogers@google.com> Cc: Adrian Hunter <adrian.hunter@intel.com> Cc: Alexander Shishkin <alexander.shishkin@linux.intel.com> Cc: Ingo Molnar <mingo@redhat.com> Cc: Jiri Olsa <jolsa@kernel.org> Cc: Mark Rutland <mark.rutland@arm.com> Cc: Namhyung Kim <namhyung@kernel.org> Cc: Peter Zijlstra <peterz@infradead.org> Link: https://lore.kernel.org/r/20240510-perf_digit-v4-3-db1553f3233b@codewreck.org Signed-off-by: Arnaldo Carvalho de Melo <acme@redhat.com>
