Message-ID: <168268425233.1877133.18332460532605313393.tglx@xen13.lab.linutronix.de>
Date: Fri, 28 Apr 2023 14:19:15 +0200 (CEST)
From: Thomas Gleixner <tglx@...utronix.de>
To: Linus Torvalds <torvalds@...ux-foundation.org>
Cc: linux-kernel@...r.kernel.org, x86@...nel.org
Subject: [GIT pull] timers/core for 6.4-rc1
Linus,
please pull the latest timers/core branch from:
git://git.kernel.org/pub/scm/linux/kernel/git/tip/tip.git timers-core-2023-04-28
up to: 158009f1b4a3: timekeeping: Fix references to nonexistent ktime_get_fast_ns()
Timekeeping and clocksource/event driver updates the second batch:
- A trivial documentation fix in the timekeeping core
- A really boring set of small fixes, enhancements and cleanups in the
drivers code. No new clocksource/clockevent drivers for a change.
Thanks,
tglx
