vhost-scsi pre-allocates the maximum sg entries per command and if a command requires more than VHOST_SCSI_PREALLOC_SGLS entries, then that command is failed by it. This patch lets vhost communicate the max sg limit when it registers vhost_scsi_ops with TCM. With this change, TCM would report the max sg entries through "Block Limits" VPD page which will be typically queried by the SCSI initiator during device discovery. By knowing this limit, the initiator could ensure the maximum transfer length is less than or equal to what is rep...
