| Subject: kselftest/vm: fix tests build with old libc |
| |
| From: Chengming Zhou <zhouchengming@bytedance.com> |
| |
| [ 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. |
