Subject: [PATCH 2/2] lockdep, bug: Exclude TAINT_OOT_MODULE from disabling lock debugging
|
|
|
|
We do want to allow lock debugging for GPL-compatible modules
|
|
that are not (yet) built in-tree. 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.
