A new CAP_USERFAULTFD is what I proposed first. :) https://lore.kernel.org/lkml/686276b9-4530-2045-6bd8-170e...
This was rejected by the capability maintainers, based on the idea that the capability would have a very narrow use case, and they want to avoid adding many more capabilities (e.g. if we add a narrow one for this use case, we might equally come up with 100s of other narrow use cases).
