I'd much rather show this in a wq sysfs file along with other related masks,
and not in a DEBUG file.
It can certainly be exposed as a permanent addition to the cgroup
control files instead of a debug only file. However this set of isolated
CPUs may be used by others not just by workqueue. So I doubt if it
should be a sysfs file in the workqueue directory. I can see if it is
possible to put a symlink there point back to the cgroupfs.
Thanks,
