SubjectRe: [PATCH V4] mm: Add sysfs interface to dump each node's zonelist information
Hi Anshuman,

[auto build test ERROR on driver-core/driver-core-testing]
[also build test ERROR on v4.8-rc5]
[cannot apply to next-20160908]
[if your patch is applied to the wrong git tree, please drop us a note to help improve the system]
[Suggest to use git(>=2.9.0) format-patch --base=<commit> (or --base=auto for convenience) to record what (public, well-known) commit your patch series was built on]
[Check https://git-scm.com/docs/git-format-patch for more information]
