v2: Fix endianness of WWNN/WWPN. [Paolo] This series implements the proposed fc_host feature of virtio-scsi. The first patch updates the data structure changes according to the spec proposal; the second patch actually implements the operations.

This patchset replace CONFIG_PM with CONFIG_PM_SLEEP for all virtio drivers and virtio pci driver. With patch 1/2, two compile warnings are eliminated for virtio pci driver, and patch 2/2 is a clean up for all virtio drivers as suggested by Amit Shah.

This patch implements the hotplug support for virtio-scsi. When there is a device attached/detached, the virtio-scsi driver will be signaled via event virtual queue and it will add/remove the scsi device in question automatically. v2: handle no_event event v3: add handle event dropped, and typo fix Signed-off-by: Sen Wang <senwang at linux.vnet.ibm.com> Signed-off-by: Cong Meng <mc at

This series implements virtio-scsi queue steering, which gives performance improvements of up to 50% (measured both with QEMU and tcm_vhost backends). This version rebased on Rusty's virtio ring rework patches, which has already gone into virtio-next today. We hope this can go into virtio-next together with the virtio ring rework pathes. V6: rework "redo allocation of target data"
