It does. In kernel memory.

I suggest to read mknod(1) manpage.

While it worked in 2.6.21, that was pretty much the only point-release
kernel where it did. In other words, I'm honestly not sure I'd
classify this as a regression given it worked exactly once :-/. So,
I'd suggest pulling this from the list for now unless Len decides
otherwise.

That should be fixed now.  It was actually a regression in 2.6.19 :)
