Subject: selftests/mm: include mman header to access MREMAP_DONTUNMAP identifier
X-Git-Tag: v6.6~20^2~1
X-Git-Url: http://git.ipfire.org/?a=commitdiff_plain;h=e2de156b0d918b5ebe975577d25f9ef92379a756;p=thirdparty%2Fkernel%2Flinux.git

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.
