checked mem_dump_obj(), but it only provides path of allocation and not of free.

/**
 * mem_dump_obj - Print available provenance information

..

 * if available, the return address and stack trace from the allocation
 * of that object.
 */
void mem_dump_obj(void *object)

and in case of "Use After Free", Free path is also required.

So we need to add support for free path in this API if we have to use it.

 

Thanks,
