I've seen it, but I don't like it too much - it can wait much longer than actually needed, and it will in most cases. > Also, I checked in the patch to mkpatch/FILES, but for full mkpatch > support there is more to be done, see the bottom of > doc/developers/new_drivers > for details. If you would do that too I would be most appreciative...
