From: Thomas Gleixner Date: Fri, 29 May 2026 20:00:12 +0000 (+0200) Subject: KVM: arm64: Use ktime_get_snapshot_id() to snapshot CLOCK_REALTIME X-Git-Url: http://git.ipfire.org/gitweb/?a=commitdiff_plain;h=744f8406a3d197b8e466d1ab09c4c3b8de8d65ea;p=thirdparty%2Fkernel%2Flinux.git KVM: arm64: Use ktime_get_snapshot_id() to snapshot CLOCK_REALTIME ktime_get_snapshot() is replaced by ktime_get_snapshot_id() which allows to request a particular CLOCK ID to be captured along with the clocksource counter. Convert the usage in kvm_get_ptp_time() over and use the new system_time_snapshot::systime field, which holds the system timestamp selected by the CLOCK ID argument. No functional change intended.
