David Hildenbrand 72ef3a3708 migration/ram: Fix error handling in ram_write_tracking_start() ... If something goes wrong during uffd_change_protection(), we would miss to unregister uffd-wp and not release our reference. Fix it by performing the uffd_change_protection(true) last. Note that a uffd_change_protection(false) on the recovery path without a prior uffd_change_protection(false) is fine.
