 +/**
 + * struct mmu_interval_notifier_finish - mmu_interval_notifier two-pass abstraction
 + * @link: Lockless list link for the notifiers pending pass list
 + * @notifier: The mmu_interval_notifier for which the finish pass is called.
 + *
 + * Allocate, typically using GFP_NOWAIT in the interval notifier's start pass.
 + * Note that with a large number of notifiers implementing two passes,
 + * allocation with GFP_NOWAIT will become increasingly likely to fail, so consider
 + * implementing a small pool instead of using kmalloc() allocations.
 + *
 + * If the implementation needs to pass data between the start and the finish passes,
 + * the recommended way is to embed struct mmu_interval_notifier_finish into a larger
 + * structure that also contains the data needed to be shared. Keep in mind that
 + * a notifier callback can be invoked in parallel, and each invocation needs its
 + * own struct mmu_interval_notifier_finish.
 + *
 + * If allocation fails, then the &mmu_interval_notifier_ops->invalidate_start op
 + * needs to implements the full notifier functionality. Please refer to its
 + * documentation.
