Subject: [PATCH v2 01/12] selftests/mm: mremap_test: remove command line options
Date: Tue, 6 Oct 2026 14:55:00 +0530 [thread overview]
Message-ID: <20261006092511.145776-2-sarthak.sharma@arm.com> (raw)
In-Reply-To: <20261006092511.145776-1-sarthak.sharma@arm.com>
mremap_test supports command line options for changing
the validation threshold and random pattern seed.
As part of a larger series to remove validation threshold
and randomization, remove all command line options from
the test. The test is already invoked without any
arguments in run_vmtests.sh, so no runner changes are
required.
