void *ptr
49  如果ptr则
50  s等于ksize - get the actual amount of memory allocated for a given object*@objp: Pointer to the object* kmalloc may internally round up allocations and return more memory* than requested. ksize() can be used to determine the actual amount of* memory allocated
52  Memoy currently used by policy/audit log/query. [TOMOYO_MEMORY_POLICY]加等于s
53  如果非Memory quota for "policy"/"audit log"/"query". [TOMOYO_MEMORY_POLICY]或Memoy currently used by policy/audit log/query. [TOMOYO_MEMORY_POLICY]小于等于Memory quota for "policy"/"audit log"/"query". [TOMOYO_MEMORY_POLICY]则返回:true
57  Memoy currently used by policy/audit log/query. [TOMOYO_MEMORY_POLICY]减等于s
