Get caught.
This should be factored out into a common helper.
Sure, will do it in next version.
Factor it out in a separate patch. Then, this patch is get small that
you can just squash it into #2.
And my comment regarding "flags = 0" to patch #2 does no longer apply :)
I see.
But it depends on if KVM_GUEST_MEMFD_ALLOW_HUGEPAGE will appear together
with initial guest memfd in linux (hopefully 6.8)

If like Paolo committed, no KVM_GUEST_MEMFD_ALLOW_HUGEPAGE in initial
merge, I will go simplify Patch #2. Otherwise factor out a common
function to get hugepage size as you suggested.
Thanks!
