perf tools: Fail properly in case pattern matching fails to find tracepoint
Currently we dont fail properly when pattern matching fails to find any
tracepoint.
Current behaviour:
$ perf record -e 'sched:krava*' sleep 1
WARNING: event parser found nothinginvalid or unsupported event: 'sched:krava*'
Run 'perf list' for a list of valid events
usage: perf record [<options>] [<command>]
or: perf record [<options>] -- <command> [<options>]
This patch change:
$ perf record -e 'sched:krava*' sleep 1
event syntax error: 'sched:krava*'
\___ unknown tracepoint
Error: File /sys/kernel/debug/tracing/events/sched/krava* not found.
Hint: Perhaps this kernel misses some CONFIG_ setting to enable this feature?.
Run 'perf list' for a list of valid events
