Swapping-over-nbd deadlock fixed?
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?

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.

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