Subject: [PATCH v2 07/12] selftests/mm: mremap_test: fail on data corruption
Date: Tue, 6 Oct 2026 14:55:06 +0530 [thread overview]
Message-ID: <20261006092511.145776-8-sarthak.sharma@arm.com> (raw)
In-Reply-To: <20261006092511.145776-1-sarthak.sharma@arm.com>
In mremap_move_multiple_vmas_split(), if data is corrupted
after mremap, the control jumps to cleanup without marking
the test as failed.
Set success to false before moving to cleanup.
Fixes: 7d6597dfef11 ("tools/testing/selftests: explicitly test split multi VMA mremap move")
Acked-by: David Hildenbrand (Arm) <david@kernel.org>
