Hi Stefan,

Your patch will work OK in a lot of settings, but there are
unfortunately also some very nasty cases where it will fail
miserably because refcounting dev_t's is not safe yet.

There are a few remaining issues to deal with before we can
properly refcount dev_t's, and that is more or less all the
places in the kernel which uses makedev().

As you may have noticed I've started evicting these from the
console related code.

Never attribute to malice what can adequately be explained by incompetence.
