Subject: [PATCH] selftests/mm: add CONFIG_DEBUG_FS to the config fragment
Date: Thu, 5 Nov 2026 12:18:01 -0500 [thread overview]
Message-ID: <20261105171801.2189772-1-sashal@kernel.org> (raw)
In-Reply-To: <4B926B36-D797-4861-B6D6-27E8D7870287@nvidia.com>
The split_huge_page and gup tests need debugfs, and CONFIG_GUP_TEST
depends on it. Add CONFIG_DEBUG_FS=y to the fragment.
Suggested-by: Zi Yan <ziy@nvidia.com>
Signed-off-by: Sasha Levin <sashal@kernel.org>
---
Merged into an x86_64 tinyconfig, the fragment leaves CONFIG_DEBUG_FS
and CONFIG_GUP_TEST unset without this change and sets both with it.
x86_64_defconfig already has CONFIG_DEBUG_FS=y and is unaffected.
