Subject: [patch 08/24] timekeeping: Remove system_time_snapshot::real/boot
Date: Tue, 26 May 2026 19:14:08 +0200	[thread overview]
Message-ID: <20260526171223.300914258@kernel.org> (raw)
In-Reply-To: 20260526165826.392227559@kernel.org

All users are converted over to ktime_get_snapshot_id() and
system_time_snapshot::sys.

Remove the leftovers.
