void **p
3754  禁止中断()
3755  以i小于size循环
3756  objp等于p[i]
3758  如果非orig_s则s等于virt_to_cache(objp)
3760  否则s等于cache_from_obj(orig_s, objp)
3762  如果非s则继续下一循环
3765  Called when kernel memory is freed (or unmapped), or if a lock* is destroyed or reinitialized - this code checks whether there is* any held lock in the memory range of to :
3766  如果非Used for retrieving partial slabs, etc. 按位与SLAB_DEBUG_OBJECTS的值则debug_check_no_obj_freed(objp, The size of an object without metadata )
3769  Release an obj back to its cache. If the obj has a constructed state, it must* be in this state _before_ it is released. Called with disabled ints.
