Was this sent to the list already? I might have missed it.

This results in unnecessary commits. I think what can do is
1) send unrelated kernel fixes that pass CI and merge them.
2) send new debugfs changes and corresponding IGT changes to the list
for review.
3) merge igt patches after kernel debugfs changes are reviewed.
4) rerun tests on the reviewed kernel patches and merge them.
