Patch was modified by Sven Eckelmann sven.eckelmann@gmx.de to apply cleanly against r1490.
Is this just modification so that it cleanly applies? Or does it also fix the deadlock?
No, deadlock isn't fixed yet. Just was nerved that it didn't apply when I wanted to test it. :)
And to the lockdep stuff. It is a real nice feature (I used it partly when debugging another kernel module), but as I noticed the mathematical correctness check is disabled on uml and cannot be enabled due to some dependency problems. :(
It is real a problem because uml is a preemption-less uniprocessor kernel and thus the spinlocks are just NOPs - so it is quite useless for any debugging of them. So back to the "lets crash my working machine" and/or qemu-based tests.
Best regards, Sven
