SubjectRe: [PATCH v3 6/8] locking/lockdep: Reuse freed chain_hlocks entries
Hi Waiman,

Thank you for the patch! Yet something to improve:

[auto build test ERROR on tip/locking/core]
[also build test ERROR on tip/auto-latest linus/master arm-perf/for-next/perf v5.5-rc6 next-20200116]
[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]
