btrfs still looks for not existing devices

["Helmut Hullen" <Hullen@t-online.de>]

Hallo, linux-btrfs,

I've just compiled kernel 3.9.04 and run

        btrfs filesystem show

On my system (Slackware 13.37, self made, without "udev") it still shows  
a lot of non existent devices (I have shortened the list ...):

Can I hope that this nasty behaviour gets fixed some day? I won't use  
"udev" just to fix it.

Viele Gruesse!
