Or you want to wait me to spin new patch set with all patches after I gather all comments?

I'm picking up the uncontrovertial, will push to my perf/core branch, continue from there, please. - Arnaldo > Thanks, > Leo Yan > > > > tools/perf/builtin-report.c | 4 ++-- > > > tools/perf/builtin-stat.c | 2 +- > > > tools/perf/builtin-top.c | 8 ++++++-- > > > tools/perf/builtin-trace.c | 5 +++-- > > > tools/perf/ui/browsers/hists.c | 13 +++++++++---- > > > tools/perf/util/annotate.c | 6 ++---- > > > tools/perf/util/cs-etm.c | 2 +- > > > tools/perf/util/intel-bts.c | 5 ++--- > > > tools/perf/util/intel-pt.c | 5 ++--- > > > tools/perf/util/map.c | 7 +++++-- > > > tools/perf/util/session.c | 3 +++ > > > 11 files changed, 36 insertions(+), 24 deletions(-) > > > > > > -- > > > 2.17.1 > > > -- - Arnaldo

Will do it. Thank you much for amendment in these patches. Leo.
When I used static checker Smatch for perf building, the main target is to check if there have any potential issues in Arm cs-etm code. So finally I get many reporting for errors/warnings. I used below command for using static checker with perf building: # make VF=1 CORESIGHT=1 -C tools/perf/ \ CHECK="/root/Work/smatch/smatch --full-path" \ CC=/root/Work/smatch/cgcc | tee smatch_reports.txt I reviewed the errors one by one, if I understood some of these errors so changed the code as I can, this patch set is the working result; but still leave some errors due to I don't know what's the best way to fix it. There also have many inconsistent indenting warnings. So I firstly send out this patch set and let's see what's the feedback from public reviewing.
