From 5340f3cb20989ec9562f7fcd65005e25b2365e6a Mon Sep 17 00:00:00 2001 From: Nam Cao Date: Mon, 3 Mar 2025 12:11:18 +0100 Subject: [PATCH] arm64/vdso: Prepare introduction of struct vdso_clock MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit 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 array of VDSO clocks. At the moment, vdso_clock is simply a define which maps vdso_clock to vdso_time_data. To prepare for the rework of the data structures, replace the struct vdso_time_data pointer with a struct vdso_clock pointer where applicable. No functional change.
