[ANNOUNCE] v4.9.30-rt21

Show all headers | View raw

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:
