Subject: [PATCH 0/5] rtc: Work around race conditions
Date: Mon,  1 Aug 2022 07:58:43 -0600	[thread overview]
Message-ID: <20220801135848.992449-1-sjg@chromium.org> (raw)

This series includes some patches to work around race conditions in the
rtc tests, as well as a mechanism to run unit tests more than once.

With 1000 runs I normally see three failures in the tests addressed here.
With this series no failures are seen.

This also includes a work-around for the daylight-saving changeover.
