This was disabled as a side-effect of commit 2449b8ba0745327c5fa49a8d9acffe03b2eded69 ('module,bug: Add TAINT_OOT_MODULE flag for modules not built in-tree'). Lock debug warnings now include taint flags, so kernel developers should still be able to deflect warnings caused by out-of-tree modules. The TAINT_PROPRIETARY_MODULE flag for non-GPL-compatible modules will still disable lock debugging.
