Dear RT folks!
I'm pleased to announce the v4.11.12-rt9 patch set.
Changes since v4.11.12-rt8:
- CPU hotplug could be rock solid now. Yes. The rewrite of the hotplug related parts for RT including rwlock's implementation over the last few weeks looks good. 'good' means that Steven's CPU-hotplug test script run a x86 box with two nodes without hanging for over a week.
- In v4.4.1-rt6 we enabled migration across scheduling while waiting for a lock [0]. As part of the hotplug rework, this optimisation is gone and the old behaviour is back.

- Reader biased RWLOCK implementation for Preempt-RT. This is an alternative RWLOCK implementation for Preempt-RT and via Kconfig off by default. Please enable it and help testing to see if something stalls (as it not writer friendly). Nothing RT related should be affected but please test your workload it to make sure.
Known issues - none so far.
