Subject: [PATCH 1/4] s390/timex: Move union tod_clock type to separate header
Date: Wed, 13 May 2026 16:01:26 +0200	[thread overview]
Message-ID: <20260513140129.4100822-2-hca@linux.ibm.com> (raw)
In-Reply-To: <20260513140129.4100822-1-hca@linux.ibm.com>

Move union tod_clock type to separate header file. This is preparation
for upcoming changes in order to avoid header dependency problems.
