6.8.3 disk activities does not respect isolcpus
My syslinux boot has:
isolcpus=32-63
Originally I discovered that when I run btrfs scrub (Main -> diskx -> scrub), it doesn't respect the isolcpus i.e. it uses the cores that are supposed to be isolated (see attached screenshot).
After a few tries, I also found other activities e.g. copying files between disks (simple cp command on console) also does not respect isolcpus.
This looks to be system independent as I can reproduce this even on Unraid as a VM.

@testdasi you are correct. I still have usage on these isolated cores, but I do have less studdering in the games I play. That being said, I've not had much chance to play any games over the last little while.
