i'll have to disagree. Some filingsystems like ntfs, arla and others that 
do 1:1 translation in their vop_bmap function DONT pass their "devvp" but 
their "vp" and thus it makes sense for them. As a compromise we could 
adjust the value of b_lblkno the same way as b_blkno is adjusted. In that 
way it would allways point to the correct lbn whatever scheme or method is 
used.
