Subject: nbd, nbdkit, loopback mounts and memory management

Hi!

I watched fosdem talk about
nbdkit... https://www.youtube.com/watch?v=9E5A608xJG0 . Nice. But word
of warning: I'm not sure using it read-write on localhost is safe.

In particular, user application could create a lot of dirty data
quickly. If there's not enough memory for nbdkit (or nbd-client or
nbd-server), you might get a deadlock.

Also note that nbd.txt in Documentation/blockdev/ points to
sourceforge; it should probably point to
https://github.com/NetworkBlockDevice/nbd ?

Best regards,

									Pavel
