Subject: [PATCH 00/19] vdso: Rework struct vdso_time_data and introduce struct vdso_clock
Date: Mon, 03 Mar 2025 12:11:02 +0100	[thread overview]
Message-ID: <20250303-vdso-clock-v1-0-c1b5c69a166f@linutronix.de> (raw)

To support multiple PTP clocks, the VDSO data structure needs to be
reworked. All clock specific data will end up in struct vdso_clock and in
struct vdso_time_data there will be an array of it.

This series is based on and intended to be merged through tip/timers/vdso.
