Subject: [PATCH] nbd: show nbd client pid in sysfs

This simple patch allows nbd to expose the nbd-client daemon's PID in 
/sys/block/nbd<x>/pid. This is helpful for tracking connection status of 
a device and for determining which nbd devices are currently in use.

Tested against 2.6.19.

Thanks,
Paul
