From 76ba7e846fcc89d9d4b25b89e303c9058de96d60 Mon Sep 17 00:00:00 2001 From: Hitoshi Mitake Date: Sat, 8 May 2010 17:10:29 +0900 Subject: 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 ... 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 Cc: Ingo Molnar Cc: Peter Zijlstra Cc: Paul Mackerras Cc: Arnaldo Carvalho de Melo Cc: Jens Axboe Cc: Jason Baron Cc: Xiao Guangrong LKML-Reference: Message-Id: <1273306229-5216-1-git-send-email-mitake@dcl.info.waseda.ac.jp> Signed-off-by: Frederic Weisbecker --- tools/perf/builtin-lock.c | 1 - 1 file changed, 1 deletion(-) diff --git a/tools/perf/builtin-lock.c b/tools/perf/builtin-lock.c index e549f4547b9..e18dfdc2948 100644 --- a/tools/perf/builtin-lock.c +++ b/tools/perf/builtin-lock.c @@ -930,7 +930,6 @@ static const struct option lock_options[] = { static const char *record_args[] = { "record", - "-a", "-R", "-f", "-m", "1024", -- cgit v1.2.3
