Hello RT-list!

I'm pleased to announce the 6.6.159-rt82 stable release.

This is Wen Yang's backport of Sebastian Andrzej Siewior's
changes to the backlog-NAPI smpboot thread mechanism from upstream
to v6.6-rt. This is actually a backport in preparation of a larger
series going back into v6.1-rt, mainly to keep parity between these
two branches in terms of RT specific changes.

You can get this release via the git tree at:

git://git.kernel.org/pub/scm/linux/kernel/git/rt/linux-stable-rt.git

branch: v6.6-rt
Head SHA1: 7fe2a2de958636b5d9bb9f9fe8894613ec014a32

Or to build 6.6.159-rt82 directly, the following patches should be applied:

https://www.kernel.org/pub/linux/kernel/v6.x/patch-6.6.159.xz

https://www.kernel.org/pub/linux/kernel/projects/rt/6.6/patch-6.6.159-rt82.patch.xz


Enjoy!
Clark
