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:
