| Subject: selftests/mm: include mman header to access MREMAP_DONTUNMAP identifier |
| Date: Thu, 12 Oct 2023 08:52:57 -0700 |
| |
| Definition for MREMAP_DONTUNMAP is not present in glibc older than 2.32 |
| thus throwing an undeclared error when running make on mm. Including |
| linux/mman.h solves the build error for people having older glibc. |
