pci-arbiter: netfs startup - chicken/egg problem

[Damien Zammit]

Hi,

I think we have another chicken/egg problem:
netfs needs an underlying node to expose pcifs on, so that the disk driver can 
start up and expose the real underlying node.

It seems like diskfs_startup_diskfs opens the real disk and finds an actual 
root fs node,
but we can't do that in netfs until the disk driver has started up.

Do I create an artificial underlying node in netfs when it is the bootstrap 
filesystem?
