Subject: selftests/vm: madv_populate: fix missing MADV_POPULATE_(READ|WRITE) definitions
X-Git-Url: http://git.maquefel.me/?a=commitdiff_plain;h=d88825f22b8f1cad8acb429b6bf0a54c85d7b93f;p=linux.git

selftests/vm: madv_populate: fix missing MADV_POPULATE_(READ|WRITE) definitions

The tests fail to compile in some environments (e.g., Debian 11.5 on x86).
Let's simply conditionally define MADV_POPULATE_(READ|WRITE) if not
already defined, similar to how the khugepaged.c test handles it.
