search for: max_id

I am pretty much new at this ROR game and had what I think to be a simple question. I have a set of Sponsors that I would like to be able to select one at random and display in the my html. I have already set up the DB, scaffolded, set index controller and all is working smoothly. I know that I can display them all by doing <% for sponsor in @sponsors %> <%= sponsor.name %>

From: Nicholas Bellinger <nab at linux-iscsi.org> This QEMU patch sets VirtIOSCSIConfig->max_target=0 for vhost-scsi operation to restrict virtio-scsi LLD guest scanning to max_id=0 (a single target ID instance) when connected to individual tcm_vhost endpoints as requested by Paolo. This ensures that virtio-scsi LLD only attempts to scan target IDs up to VIRTIO_SCSI_MAX_TARGET when connected via virtio-scsi-raw. It's currently cut against Zhi's qemu vhost-scsi tree...

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"

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,

This series adds an initial implementation for scrub. It works quite straightforward. The usermode issues an ioctl for each device in the fs. For each device, it enumerates the allocated device chunks. For each chunk, the contained extents are enumerated and the data checksums fetched. The extents are read sequentially and the checksums verified. If an error occurs (checksum or EIO), a good copy
