So, in the process of receiving the fake message the lkb flags would be updated and cleared from the zero flags in the message. The problem observed in tests was the loss of the USER flag which caused the dlm to think a user lock was a kernel lock and subsequently fail an assertion checking the validity of the ast/callback field.
