Subject: Re: [PATCH v5 03/10] perf: Use min_max_heap in visit_groups_merge

Hi Ian,

Thank you for the patch! Yet something to improve:

[auto build test ERROR on tip/perf/core]

[if your patch is applied to the wrong git tree, please drop us a note to help
improve the system. BTW, we also suggest to use '--base' option to specify the
base tree in git format-patch, please see https://stackoverflow.com/a/37406982]

Note: the linux-review/Ian-Rogers/Optimize-cgroup-context-switch/20191208-065350 HEAD 90f4b194c2271d12b02888811e887a869d1e3817 builds fine.
      It only hurts bisectibility.

All errors (new ones prefixed by >>):
