mn_hlist_releaseThis function can't run concurrently against mmu_notifier_register* because mm->mm_users > 0 during mmu_notifier_register and exit_mmap* runs with mm_users == 0
mmu_notifier_unregisterThis releases the mm_count pin automatically and frees the mm* structure if it was the last user of it. It serializes against* running mmu notifiers with SRCU and against mmu_notifier_unregister* with the unregister lock + SRCU
mmu_notifier_putmmu_notifier_put - Release the reference on the notifier*@mn: The notifier to act on* This function must be paired with each mmu_notifier_get(), it releases the* reference obtained by the get. If this is the last reference then process
