From e2de156b0d918b5ebe975577d25f9ef92379a756 Mon Sep 17 00:00:00 2001 From: Samasth Norway Ananda Date: Thu, 12 Oct 2023 08:52:57 -0700 Subject: [PATCH] selftests/mm: include mman header to access MREMAP_DONTUNMAP identifier 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.
