Hello!

The "[PATCH] devfs: switch over ubd to ->devfs_name" patch that was included into 2.5.68,
have broken UML's ubd/sysfs interaction.
Sysfs is very upset when something tries to register several devices with
same name, so I was forced to use following patch.
If this is wrong, then please explain to me why, and suggest the correct way of handling
this situation.

Thank you.

Bye,
Oleg
