hi, adding support to enable/disable specific events via control file via following commands:
# echo 'enable sched:sched_process_fork' > control # echo 'disabled sched:sched_process_fork' > control
v3 changes: - use ' ' instead of '-' in syntax and add command argument processing [Arnaldo] - add options to evlist [Arnaldo] - add man page changes
v2 changes: - added acks - change list to evlist [Arnaldo] - add evlist-verbose command [Arnaldo] - add '' to enale-/disable- error message
The code is available in here: git://git.kernel.org/pub/scm/linux/kernel/git/jolsa/perf.git perf/control
thanks, jirka
