Ah, I was looking at

git log stable/linux-5.15.y --author "David Hildenbrand"

And didn't spot the patches.

In my inbox I indeed see from 03/21 and 03/23

Patch "mm/hugetlb: fix excessive IPI broadcasts when unsharing
PMD tables using mmu_gather" has been added to the 6.1-stable
tree

and

Patch "mm/hugetlb: fix excessive IPI broadcasts when unsharing
PMD tables using mmu_gather" has been added to the 5.15-stable
tree

So that should indeed be on its way.

The 5.10 backport might still be missing:

At least I didn't find a related mail in my inbox.

Thanks Greg!
