7 * This implements a refcount with similar semantics to atomic_t - atomic_inc(),
8 * atomic_dec_and_test() - but percpu.
15 * The refcount will have a range of 0 to ((1U << 31) - 1), i.e. one bit less
16 * than an atomic_t - this is because of the way shutdown works, see
20 * refcount hitting 0 - it can't, if it was in percpu mode. percpu_ref_kill()
21 * puts the ref back in single atomic_t mode, collecting the per cpu refs and
22 * issuing the appropriate barriers, and then marks the ref as shutting down so
23 * that percpu_ref_put() will check for the ref hitting 0. After it returns,
24 * it's safe to drop the initial ref.
