If you fix the issue, kindly add following tag as appropriate Reported-by: kernel test robot lkp@intel.com
All errors (new ones prefixed by >>):
mm/huge_memory.c:3026:40: error: implicit declaration of function 'vma_migratable' [-Werror,-Wimplicit-function-declaration]
if (!vma || addr < vma->vm_start || !vma_migratable(vma)) ^1 error generated.
There is no need to call vma_migratable() here. Will remove it.
Thanks for catching it.
