If the source and destination file are identical, the receiving scp truncates the file. On the sending end, read() returns 0, and garbage is sent instead of actual data, and the receiving end puts it into the file, which at least confuses the users. -- Florian Weimer Florian.Weimer at RUS.Uni-Stuttgart.DE University of Stuttgart http://cert.uni-stuttgart.de/

Hi When NetBSD added strnvis they swapped around the argument order. On OpenBSD: int strnvis(char *, const char *, size_t, int) On NetBSD: int strnvis(char *, size_t, const char *, int); Don't ask me why.

Hi, These patches try to support multi virtual queues(multi-vq) in one virtio-blk device, and maps each virtual queue(vq) to blk-mq's hardware queue. With this approach, both scalability and performance on virtio-blk device can get improved. For verifying the improvement, I implements virtio-blk multi-vq over qemu's dataplane feature, and both handling host notification from each vq and

Seems to work OK for native and Xen. I had to play a bit with the paravirt-sched-clock patch to deal with the VMI changes. Zach, can you check that it still works? Thanks, J
