Subject: [patch 0/7] posix-timers: Prepare for PREEMPT_RT - part 1
Date: Wed, 31 Jul 2019 00:33:48 +0200	[thread overview]
Message-ID: <20190730223348.409366334@linutronix.de> (raw)

The following series prepares posix-timers for RT. The main change here is
to utilize the hrtimer synchronization mechanism to prevent priority
inversion and live locks on timer deletion.

This does not cover the posix CPU timers as they need more special
treatment for RT which is covered in a separate series.

Applies on top of:

   git://git.kernel.org/pub/scm/linux/kernel/git/tip/tip.git timers/core

Thanks,

	tglx
