Hi,
I've got a some weird problems and I've been chasing
them for quite some time. I know I have done something
stupid while testing like hell but I can't really
figure it out.
And I still get oops from time to time but I think
this has nothing to do with the lvs-patch.
And I attached a small beautifier patch:
- I think the #ifdef / #endif is not needed anymore.
- corrected little typo I saw while reading the code.
regards,
Roberto Nibali, ratz
