#     fs/userfaultfd: Fix maple tree iterator in userfaultfd_unregister()
#     
#     When iterating the VMAs, the maple state needs to be invalidated if the
#     tree is modified by a split or merge to ensure the maple tree node
#     contained in the maple state is still valid.  These invalidations were
#     missed, so add them to the paths which alter the tree.
#

#     Fixes: 69dbe6daf104 (userfaultfd: use maple tree iterator to iterate VMAs)
