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 <mitake@dcl.info.waseda.ac.jp> Cc: Ingo Molnar <mingo@elte.hu> Cc: Peter Zijlstra <a.p.zijlstra@chello.nl> Cc: Paul Mackerras <paulus@samba.org> Cc: Arnaldo Carvalho de Melo <acme@redhat.com> Cc: Jens Axboe <jens.axboe@oracle.com> Cc: Jason Baron <jbaron@redhat.com> Cc: Xiao Guangrong <xiaoguangrong@cn.fujitsu.com> LKML-Reference: Message-Id: <1273306229-5216-1-git-send-email-mitake@dcl.info.waseda.ac.jp> Signed-off-by: Frederic Weisbecker <fweisbec@gmail.com>
