clru等于common_lru

439

cpu等于These macros fold the SMP functionality into a single CPU system()

441

loc_l等于per_cpu_ptr(local_list, cpu)

443

raw_spin_lock_irqsave( & lock, flags)

445

node等于__local_list_pop_free(loc_l)

446

如果非node则

447

bpf_lru_list_pop_free_to_local(lru, loc_l)

448

node等于__local_list_pop_free(loc_l)

451

如果node则__local_list_add_pending(lru, loc_l, cpu, node, hash)

454

raw_spin_unlock_irqrestore( & lock, flags)

456

如果node则返回:node
