Yes, bt -FF helps much. However, the pointer in stack is address in middle of object data in many times. E.g. for ext4_inode_cache, "struct address_space *" is in stack. But actual slab object is inode->i_mapping == ext4_inode_info.vfs_inode.i_data. Or functions takes member of object, e.g., &object->list. If there is easy way to get the object address from the field of object address, it would be what I want.
