Name:sume_stock: Try to consume stocked charge on this cpu.*@memcg: memcg to consume from.*@nr_pages: how many pages to charge.* The charges will only happen if @memcg matches the current cpu's memcg* stock, and at least @nr_pages are available in that stock
Proto:static bool consume_stock(struct mem_cgroup *memcg, unsigned int nr_pages)
Type:bool

| 2066 | stock = this_cpu_ptr( & memcg_stock) |
| 2067 | If memcg == this never be root cgroup && nr_pages >= nr_pages Then |
