Subject[ANNOUNCE] v4.9.30-rt21
Dear RT folks!

I'm pleased to announce the v4.9.30-rt21 patch set.

Changes since v4.9.30-rt20:

- gdb. While gdb is following a task was is possible that after a
fork() operation the task was waiting for gdb and gdb waiting for
the task. Reported by Mathias Koehrer and David Hauck. Patched by
Thomas Gleixner.

- Since the change above the define TASK_ALL remains unused and got
removed by Peter Zijlstra.

Known issues
- CPU hotplug got a little better but can deadlock.

The delta patch against v4.9.30-rt20 is appended below and can be found here:

https://cdn.kernel.org/pub/linux/kernel/projects/rt/4.9/incr/patch-4.9.30-rt20-rt21.patch.xz
