perf lock: Drop "-a" option from cmd_record() default arguments set
This patch drops "-a" from the default arguments passed to
perf record by perf lock.
If a user wants to do a system wide record of lock events,
perf lock record -a <program> <argument> ...
is enough for this purpose.
This can reduce the size of the perf.data file.
% sudo ./perf lock record whoami
root
[ perf record: Woken up 1 times to write data ]
[ perf record: Captured and wrote 0.439 MB perf.data (~19170 samples) ]
% sudo ./perf lock record -a whoami # with -a option
root
[ perf record: Woken up 0 times to write data ]
[ perf record: Captured and wrote 48.962 MB perf.data (~2139197 samples) ]
