[Qemu-devel] [PULL 2/3] block/nfs: try to avoid the bounce buffer in pwritev

[Jeff Cody]

From: Peter Lieven <pl@kamp.de>

if the passed qiov contains exactly one iov we can
pass the buffer directly.

[Qemu-devel] [PULL 3/3] RBD: Add support readv,writev for rbd

[Jeff Cody]

From: tianqing <tianqing@unitedstack.com>

Rbd can do readv and writev directly, so wo do not need to transform
iov to buf or vice versa any more.
