Subject: [PATCH v1 1/3] kunit: fix bug in debugfs logs of parameterized tests
Date: Tue, 31 Jan 2023 22:03:53 +0000	[thread overview]
Message-ID: <20230131220355.1603527-2-rmoar@google.com> (raw)
In-Reply-To: <20230131220355.1603527-1-rmoar@google.com>

Fix bug in debugfs logs that causes parameterized results to not appear
in the log because the log is reintialized (cleared) when each parameter is
run.

Ensure these results appear in the debugfs logs and increase log size to
allow for the size of parameterized results.
