That is a very good question. I removed 160 people from the original
e-mail and left the ones that where previously involved with this patch
and left all the lists for good measure. But it seems I can reduce it
even more.

How about this: For these treewide efforts I just leave the people that
are/were involved in the series and add two lists: linux-kernel and
linux-hardening.

Unless someone screams, I'll try this out on my next treewide.

Thx for the feedback

Best
