Dear RT folks!
I'm pleased to announce the v5.10-rc5-rt11 patch set.
Changes since v5.10-rc5-rt10:
- The workaround for the IMX clock driver failure has been replaced
with a another patch which was proposed upstream.
- Tweak the rtmutex patches to build a allnoconfig with RT enabled.
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 v5.10-rc5-rt10 is appended below and can be found here:
https://cdn.kernel.org/pub/linux/kernel/projects/rt/5.10/incr/patch-5.10-rc5-rt10-rt11.patch.xz
You can get this release via the git tree at:
git://git.kernel.org/pub/scm/linux/kernel/git/rt/linux-rt-devel.git v5.10-rc5-rt11
The RT patch against v5.10-rc5 can be found here:
https://cdn.kernel.org/pub/linux/kernel/projects/rt/5.10/older/patch-5.10-rc5-rt11.patch.xz
The split quilt queue is available at:

It seems that the v5.10-rc5-rt11 tag was not pushed:
```
$ git fetch rt-devel --tags
