I've ported strglobmatch from perf-tools (with recursive call limitation) for this use. It is easier to use (just replacing strcmp) but slower than current parser-based matching. I don't care about the speed of matching because the all of the matching which I've introduced in this series are done on slow-path. --- Masami Hiramatsu (5): [BUGFIX] tracing: Returns -EBUSY when event_enable_func fails to get module perf: Reorder parameters of strglobmatch lib/string: Add a generic wildcard string matching function tracing/kprobes: Allow user to delete kprobe events by wild cards tracing: Support enable/disable multiple events trigger by wild cards Documentation/trace/ftrace.txt | 12 ++- Documentation/trace/kprobetrace.txt | 19 +++-- include/linux/string.h | 8 ++ kernel/trace/trace_events.c | 121 +++++++++++++++++++++++++---------- kernel/trace/trace_kprobe.c | 97 ++++++++++++++++++++-------- lib/string.c | 91 ++++++++++++++++++++++++++ tools/perf/util/parse-events.c | 14 ++-- tools/perf/util/probe-event.c | 2 - tools/perf/util/strfilter.c | 2 - tools/perf/util/string.c | 16 ++--- tools/perf/util/util.h | 4 + 11 files changed, 295 insertions(+), 91 deletions(-) -- Masami Hiramatsu IT Management Research Dept. and Linux Technology Center Hitachi, Ltd., Yokohama Research Laboratory
