KVM: guest_memfd: implement userfaultfd operations

2026-04-03T06:50:24Z

userfaultfd notifications about page faults used for live migration and snapshotting of VMs. MISSING mode allows post-copy live migration and MINOR mode allows optimization for post-copy live migration for VMs backed with shared hugetlbfs or tmpfs mappings as described in detail in commit 7677f7fd8be7 ("userfaultfd: add minor fault registration mode"). To use the same mechanisms for VMs that use guest_memfd to map their memory, guest_memfd should support userfaultfd operations. Add implementation of vm_uffd_ops to guest_memfd.

mm: change to return bool for the MMU notifier's young flag check

2026-04-01T23:11:04Z

The MMU notifier young flag check related functions only return whether the young flag was set. Change the return type to bool to make the intention clearer.
