Hi!
I played a bit with -rt kernels, and here are the results.

Thanks for picking this up.

v4.19.50-rt22-cip3-rebase was reasonably easy to do, as -cip1 was
empty. v4.4.179-rt181-cip34-rebase was more interesting.
Trees are at kernel.org:
https://git.kernel.org/pub/scm/linux/kernel/git/pavel/linux-cip.git/log/?h=v4.4.179-rt181-cip34-rebase
https://git.kernel.org/pub/scm/linux/kernel/git/pavel/linux-cip.git/log/?h=v4.19.50-rt22-cip3-rebase
Basically untested. Could I ask for reviews and testing?
I know that full preemption does not work on x86-32. I sent
"PREEMPT_RT_FULL on x86-32 machine" mail to the lists
I don't know how to release useful non-rebasing trees. Is someone
using those?

Just like the regular -cip kernel, the -rt version's primary stable feed is merge-based. Rebasing only comes out of the fact that a second patch series is involved, but I doubt many folks use that feed as source. I don't, my colleagues neither (AFAIK).

Please sync with Daniel Wagner on the workflow options and also on 4.4-rt maintenance.
