[ Upstream commit b773827e361952b3f53ac6fa4c4e39ccd632102e ]
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.
