Description Petr Cervinka 2023-11-13 11:55:42 UTC 
tuned started to produce error on 15-SP6 since was kernel upgraded to 6.4.0.

2023-11-13 06:41:26,384 ERROR    tuned.utils.commands: Executing sysctl error: sysctl: cannot stat /proc/sys/kernel/sched_min_granularity_ns: No such file or directory
2023-11-13 06:41:26,387 ERROR    tuned.utils.commands: Executing sysctl error: sysctl: cannot stat /proc/sys/kernel/sched_wakeup_granularity_ns: No such file or directory

Error is obvious, sched_wakeup_granularity_ns is now in /sys/kernel/debug/sched/ with new kernel and tuned seems to be outdated for it.

tuned version in 15-SP6 is  2.10.0-150400.19.10.
tuned version on Tumbleweed is 2.21.0.0+ and works fine.

Should be also tuned updated in 15-SP6 to support latest kernel?
