I backported the recent gntdev patches to stable branches before 5.15.
The first patch is a prerequisite for the other backports.  The second
patch should apply cleanly to all stable branches, but the third only
applies to 5.10 as it requires mmu_interval_notifier_insert_locked().

Jan Beulich (1):
  Xen/gntdev: don't ignore kernel unmapping error

M. Vefa Bicakci (2):
  xen/gntdev: Prevent leaking grants
  xen/gntdev: Accommodate VMA splitting
