similar to: [PATCH] [SCSI] virtio-scsi: Add real 2-clause BSD license to header

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 Signed-off-by: Cong Meng <mc at linux.vnet.ibm.com> Signed-off-by: Sen Wang <senwang at linux.vnet.ibm.com> ---

James, patch 1 fixes scanning of LUNs whose number is greater than 255. QEMU passes a max_lun of 16383 (because it uses SAM numbering) but in Linux it must become 32768 (because LUNs above 255 are "relocated" to 16640). Patch 2 is a resubmission of the patch for online resizing of virtio-scsi LUNs, which needs to be rebased. LUNs above 255 now work for all of scanning, hotplug,

Commit 5ff843721467 ("scsi: virtio_scsi: unplug LUNs when events missed"), almost fixed the case of mass unpluging of LUNs, but it missed a corner case in which all the LUNs are unplugged at the same time. In this case INQUIRY ends with DID_BAD_TARGET. Detect this and unplug the LUN. Signed-off-by: Maxim Levitsky <mlevitsk at redhat.com> --- drivers/scsi/virtio_scsi.c | 10
