Move the overflow check for sgl_count > TCM_VHOST_PREALLOC_SGLS into
vhost_scsi_map_iov_to_sgl() so that it's based on the total number
of SGLs for all IOVs, instead of single IOVs.
Also, rename TCM_VHOST_PREALLOC_PAGES -> TCM_VHOST_PREALLOC_UPAGES
to better describe poi

This patch updates vhost_scsi_handle_vq() to check for the existance
of virtio_scsi_cmd_req_pi comparing vq->iov[0].iov_len in order to
calculate seperate data + protection SGLs from data_num.
Also update tcm_vhost_submission_work() to pass the pre-allocated
cmd->tvc_pro
From: Nicholas Bellinger
This patch updates tcm_vhost_make_nexus() to pre-allocate per descriptor
tcm_vhost_cmd->tvc_prot_sgl[] used to expose protection SGLs from within
virtio-scsi guest memory to vhost-scsi.

This patch updates virtscsi_probe() to setup necessary Scsi_Host
level protection resources. (currently hardcoded to 1)
It changes virtscsi_add_cmd() to attach outgoing / incoming
protection SGLs preceeding the data payload, and is using the
new virtio_scsi_cmd_req_pi->d
From: Nicholas Bellinger
This patch adds vhost_scsi_map_iov_to_prot() to perform the mapping of
T10 data integrity memory between virtio iov + struct scatterlist using
get_user_pages_fast() following existing code.
As with vhost_scsi_map_iov_to_sgl(), this does sanity checks against the
total pr

Hi MST, MKP, Paolo & Co,
This is an updated patch series for adding T1O protection information (PI)
SGL passthrough support between virtio-scsi LLD + vhost-scsi fabric
endpoints.
Following Paolo's recommendations, this patch uses VIRTIO_SCSI_F_T10_PI
feature bits in bot
From: Nicholas Bellinger
This patch adds a virtio_scsi_cmd_req_pi header as recommened by
Paolo that contains do_pi_niov + di_pi_niov elements used for
signaling when protection information buffers are expected to
preceed the data buffers.
Also add new VIRTIO_SCSI_F_T10_PI feature bit to be used
