# \[patch 08/24\] timekeeping: Remove system\_time\_snapshot::real/boot - From: Thomas Gleixner \ - Date: 2026-05-26 17:14:11 - List: netdev - Page: https://ratatoskr.run/netdev/2026/05/17032604 - Thread: https://ratatoskr.run/kvmarm/2026/05/17032577/t.md ```text All users are converted over to ktime_get_snapshot_id() and system_time_snapshot::sys. Remove the leftovers.
