I'll post the alternative approach for fixing the unlocking bug next week (need to test, and I'm out of time this week). Regarding the initialize/invalidate hooks, I resurrected the discussion from the previous version[*], I'd like to bottom out on a solution in that thread before applying anything.

From: Isaku Yamahata <isaku.yamahata@intel.com> This patch series for KVM guest memfd is to have common code base for SEV and TDX. Several minor fixes.
