Your template is off here.

Yes, this was the intention of the exercise :) > Known issues: > > sigwaittest with hackbench as workload is able to trigger a crash on x86_64, > the same as reported for the v4.4.220-rt196 release.

In v5.4.3-rt1 there is fe18e9e08e25d ("BPF: Disable on PREEMPT_RT")
so maybe backport this across the stable kernels. Fixing it is a way larger queue. If the intention is to keep it disabled it could be enforced via Kconfig so it is not enabled by accident (or by using oldconfig on a distro config which has it enabled).
