Subject: Re: [PATCH v2 1/4] mm: define MAX_PTRS_PER_{PTE,PMD,PUD}
Hi Daniel,
Thank you for the patch! Perhaps something to improve:
[auto build test WARNING on next-20191209]
[also build test WARNING on linus/master v5.5-rc1]
[cannot apply to powerpc/next asm-generic/master v5.4]
[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]
