Kulikov Vasiliy had written, on 07/30/2010 06:09 AM, the following:
dbll_create() leaks pzl_target if target_obj is NULL. Call kzalloc()
only if memory is used.

I would suggest to add a else branch for if (target_obj != NULL) adding a status =-ENOMEM if error.

Overall, I guess we need to kick out the DBC_REQUIRE usage.. it is misleading as it is active only when DEBUG macro is enabled!
