The lock order reversal warnings are a fault with current at the
moment. If I had my way the cause would be backed out until there
is a solution. I understand that it is a witness improvment that
has caused the warnings to start appearing.... meaning that the
change has exposed an existing problem that wasn't warned obut
before.
They certainly aren't DTrace change specific.
