Subject: [PATCH mm-unstable v1 2/4] selftests/vm: madv_populate: fix missing MADV_POPULATE_(READ|WRITE) definitions
Date: Mon, 5 Dec 2022 20:37:14 +0100 [thread overview]
Message-ID: <20221205193716.276024-3-david@redhat.com> (raw)
In-Reply-To: <20221205193716.276024-1-david@redhat.com>
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.
Fixes: 39b2e5cae43d ("selftests/vm: make MADV_POPULATE_(READ|WRITE) use in-tree headers")
Signed-off-by: David Hildenbrand <david@redhat.com>
