Kernel server for GNBD + raid1+(g)nbd.

[Marcelo Tosatti]

I used the Jeff Becker's knbd server code to write a kgnbd server. 
It works fine and i'll benchmark it with bonnie tomorrow if i find some
time. The only thing missing is killing the client threads on rmmod. 
Hope to find time to do that tomorrow. 
The code can be found at http://bazar.conectiva.com.br/~marcelo/ha/kgnbd/.
I've written a mini mini HOWTO about RAID1+NBD+ my RAID write-only
patches. It can be found at
http://bazar.conectiva.com.br/~marcelo/ha/raidwo. (Alan, you can put
these page on the Linux HA site if you desire).
