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

[Joseph Salisbury]

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
