From: Arnaldo Carvalho de Melo Date: Tue, 14 Aug 2012 19:35:48 +0000 (-0300) Subject: perf evlist: Rename __group method to __set_leader X-Git-Url: https://git.stricted.de/?a=commitdiff_plain;h=63dab225f334e0e21f7106aed8d888b500b53ce6;p=GitHub%2FLineageOS%2Fandroid_kernel_motorola_exynos9610.git perf evlist: Rename __group method to __set_leader Just like was done for parse_events__set_leader. Also we need to have the list_entry set_leader method in evlist.c so that we don't grow another dep in the python binding: # ~acme/git/linux/tools/perf/python/twatch.py Traceback (most recent call last): File "/home/acme/git/linux/tools/perf/python/twatch.py", line 16, in import perf ImportError: /home/acme/git/build/perf/python/perf.so: undefined symbol: parse_events__set_leader And also remove a pr_debug from evsel.c so that we avoid this one too: # ~acme/git/linux/tools/perf/python/twatch.py Traceback (most recent call last): File "/home/acme/git/linux/tools/perf/python/twatch.py", line 16, in import perf ImportError: /home/acme/git/build/perf/python/perf.so: undefined symbol: eprintf Acked-by: Jiri Olsa Acked-by: Namhyung Kim Cc: David Ahern Cc: Frederic Weisbecker Cc: Jiri Olsa Cc: Mike Galbraith Cc: Namhyung Kim Cc: Paul Mackerras Cc: Peter Zijlstra Cc: Stephane Eranian Link: http://lkml.kernel.org/n/tip-0hk9dazg9pora9jylkqngovm@git.kernel.org Signed-off-by: Arnaldo Carvalho de Melo --- diff --git a/tools/perf/builtin-record.c b/tools/perf/builtin-record.c index f5b6137c0f7e..c4e3b683e79b 100644 --- a/tools/perf/builtin-record.c +++ b/tools/perf/builtin-record.c @@ -193,7 +193,7 @@ static void perf_record__open(struct perf_record *rec) perf_evlist__config_attrs(evlist, opts);
