Thanks for the offer, but I'd rather keep this one standalone: it's a
stable fix, and it shouldn't have to wait for the debugfs series.  If it
goes in first, your 1/6 just needs to keep &p->cpus_mask on that line:

	if (!cpumask_subset(rd->span, &p->cpus_mask) ||
	    rd->dl_bw.bw == 0) {

If the maintainers would rather have it in your series, I'm fine with
that, as the first patch and with its authorship and its Fixes and
stable tags unchanged.

That tag is gone as of v7.4-rc1, which this patch is based on: commit
1e035297ffda ("docs: remove Assisted-by references") dropped it from
coding-assistants.rst and checkpatch.  tip/sched/core is still on an
older base, where the docs have it.

Per Documentation/process/generated-content.rst, the tool was Claude
Code with Claude Opus 5.5.  It helped find the bug and write the patch,
its changelog and its test, and I reviewed the result.

Thanks,
