[ANNOUNCE] v5.9.1-rt20v5.9.1-rt20-patches

Dear RT folks!

I'm pleased to announce the v5.9.1-rt20 patch set.

Changes since v5.9.1-rt19:

  - Tiny update to the rtmutex patches (make __read_rt_trylock()
    static).

  - The test_lockup module failed to compile. Reported by Fernando
    Lopez-Lezcano.

  - The `kcompactd' daemon together with MEMCG could have accessed
    per-CPU variables in preemtible context.

  - The patch for the crash in the block layer (previously reported by
    David Runge) has been replaced with another set of patches which
    were submitted upstream.

Known issues
     - It has been pointed out that due to changes to the printk code the
       internal buffer representation changed. This is only an issue if tools
       like `crash' are used to extract the printk buffer from a kernel memory
       image.

The delta patch against v5.9.1-rt19 is appended below and can be found here:
