The error message when I build vm tests on debian10 (GLIBC 2.28): userfaultfd.c: In function ‘userfaultfd_pagemap_test’: userfaultfd.c:1393:37: error: ‘MADV_PAGEOUT’ undeclared (first use in this function); did you mean ‘MADV_RANDOM’? if (madvise(area_dst, test_pgsize, MADV_PAGEOUT)) ^~~~~~~~~~~~ MADV_RANDOM This patch includes these newer definitions from UAPI linux/mman.h, is useful to fix tests build on systems without these definitions in glibc sys/mman.h.
