You might want to Cc to him directly: I hear he filters his mail. I certainly do (stuff Cc'ed or just sent directly gets read sooner than kernel-list stuff).

People who don't like the new names can always use the compatibility names. Although in my personal setup I disable the compatibility entries (I've put my money where my mouth is;-).

I'm still considering hacking the SCSI disc driver to support >16 discs by using the devfs automagic device numbering. I just haven't had time to do it. A volunteer would be welcome. Hint, hint.

Yep, that compatibility is essential. I even used it myself when only a few drivers supported devfs :-)
