* All four percpu_ref_*() operations implemented in the header file perform the same operation to determine whether the percpu_ref is alive and extract the percpu pointer. Factor out the common logic into __pcpu_ref_alive(). This doesn't change the generated code. * There are a couple places in percpu-refcount.c which masks out PCPU_REF_DEAD to obtain the percpu pointer. Factor it out into pcpu_count_ptr(). * The above changes make the WARN_ON_ONCE() conditional at the top of percpu_ref_kill_and_confirm() the only user of REF_STATUS(). Test PCPU_REF_DEAD directly and remove REF_STATUS(). This patch doesn't introduce any functional change.
