Subject: [patch 0/4] timer/nohz: Fix timer/nohz woes
Date: Fri, 22 Dec 2017 15:51:11 +0100 [thread overview]
Message-ID: <20171222145111.919609918@linutronix.de> (raw)
Paul was observing weird stalls which are hard to reproduce and decode. We
were finally able to reproduce and decode the wreckage on RT.
The following series addresses the issues and hopefully nails the root
cause completely.
Please review carefully and expose it to the dreaded rcu torture tests
which seem to be the only way to trigger it.
Thanks,
tglx
