The bug is not related to swapping via nbd.
The problem happens because the allocation code (kmalloc) which is called
inside the nbd request function can end up trying to sync dirty buffers,
going to back to the nbd request function.
2.4 is safe.

I see in the 2.2.18 release notes that a deadlock, related to swapping
over a network via nbd, was fixed. Is this bug present in 2.4.x-test?

It _should_ be fixed in 2.4 as well. Then again, I don't know
if there are any other deadlocks left .. ;)
