Hello, are LockOrderReversal something to worry about? I ask because I see 
the list growing but it doesn't seem it's anything relevant for the 
Release process, so I guess they can be ignored by non kernel devolpers. 
Is this correct? If not, and LORs are serious errors, will 6.0 be shipped 
with all these errors?!? Well those from this message were on 7.0, but I 
guess the first hundred are in 6.0...

Best regards,
