Subject: out-of-tree module shouldn't disable lockdep
Date: Thu, 22 Dec 2011 08:59:52 -0800	[thread overview]
Message-ID: <20111222165952.GH17084@google.com> (raw)

Hello, guys.

2449b8ba074 "module,bug: Add TAINT_OOT_MODULE flag for modules not
built in-tree" added TAINT_OOT_MODULE to mark kernel which has
out-of-tree module loaded, which might be a good idea but an
unfortunate side effect of tainting is that it disables lockdep.  So,
now, none of my test modules is watched by lockdep.  This is a bad bad
idea.  People use oot modules to write test code and disabling lockdep
for test codes is silly.  Can we please fix this?

Thanks.
