Since\nptep_modify_prot_start() gets and clears atomically, the following is the\ncorrect pattern and prevents any possible race.  Any access after the\nfirst call would see an invalid pte and cause a fault:\n\n  pte = ptep_modify_prot_start(ptep);\n  pte = pte_mkuffd_wp(pte);\n  ptep_modify_prot_commit(ptep, pte);"
