[RFC} Commit 8a99b6833c88 Moves Important Real-time Settings To DebugFS

Hello,
Some Ubuntu users are using the tuned package with a 5.15.x based
real-time kernel. Tuned adjusts various sysctl options based on a
specified profile. This userspace package has stopped working > 5.13
due to the following commit:
8a99b6833c88 "(sched: Move SCHED_DEBUG sysctl to debugfs)"
This commit moved some important real-time sysctl knobs to debugfs in
5.13-rc1. It also appears some of the sysctl options were not moved,
sched_min_granularity_ns, for example.
I was hoping to get some feedback on how to approach this. Would
upstream real-time consider accepting a patch to the 5.15 real-time
patch set that reverts this commit? Or a new patch that adds the sysctl
settings back? Any other ideas or feedback would be appreciated!
Thanks in advance,
Joe
