[ Upstream commit b773827e361952b3f53ac6fa4c4e39ccd632102e ] |
| 9 |

The error message when I build vm tests on debian10 (GLIBC 2.28): |
| 11 |
|
| 12 |
userfaultfd.c: In function `userfaultfd_pagemap_test': |
| 13 |
userfaultfd.c:1393:37: error: `MADV_PAGEOUT' undeclared (first use |
| 14 |
in this function); did you mean `MADV_RANDOM'? |
| 15 |
if (madvise(area_dst, test_pgsize, MADV_PAGEOUT)) |
| 16 |
^~~~~~~~~~~~ |
| 17 |
MADV_RANDOM |
| 18 |
|
| 19 |
This patch includes these newer definitions from UAPI linux/mman.h, is |
| 20 |
useful to fix tests build on systems without these definitions in glibc |
| 21 |
sys/mman.h. |
