Subject: [PATCH] selftests/mm: include linux/mman.h for prctl_thp_disable
Date: Wed, 10 Sep 2025 21:46:09 +0100 [thread overview]

MADV_COLLAPSE is part of linux/mman.h and needs to be included
for this selftest for glibc compatibility. It is also included
in other tests that use MADV_COLLAPSE.

Reported-by: Mark Brown <broonie@kernel.org>
