The patch below does not apply to the 5.7-stable tree. If someone wants it applied there, or to any other stable or longterm tree, then please email the backport, including the original git commit id to stable@vger.kernel.org.
Oops, I applied things out of order, I've queued this and the 5.4 version up, but 4.19 doesn't apply as the dependant patch does not apply.
Something like this should work?
Nope. Unless I am misreading the old code you are udner pgdat_resize_lock. Or is there any other change queued before this backport to remove the lock? (I didn't get to check more closely but it would be 3d060856adfc5 IIRC).
