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) ] Signed-off-by: Hitoshi Mitake <[email protected]> Cc: Ingo Molnar <[email protected]> Cc: Peter Zijlstra <[email protected]> Cc: Paul Mackerras <[email protected]> Cc: Arnaldo Carvalho de Melo <[email protected]> Cc: Jens Axboe <[email protected]> Cc: Jason Baron <[email protected]> Cc: Xiao Guangrong <[email protected]> LKML-Reference: Message-Id: <[email protected]> Signed-off-by: Frederic Weisbecker <[email protected]>
