Subject: [PATCH] selftests/mm: fix split huge page tests
Date: Mon,  6 Mar 2023 11:09:07 -0500	[thread overview]
Message-ID: <20230306160907.16804-1-zi.yan@sent.com> (raw)

From: Zi Yan <ziy@nvidia.com>

Fixed two inputs to check_anon_huge() and one if condition, so the tests
work as expected.

Fixes: c07c343cda8e ("selftests/vm: dedup THP helpers")
