[GIT PULL] target updates for v3.10-rc1

[Nicholas A. Bellinger]

Hello Linus!

Here are the target pending changes for the v3.10-rc1 merge window.  

Please go ahead and pull from:

  git://git.kernel.org/pub/scm/linux/kernel/git/nab/target-pending.git for-next-merge

The highlights this round include:

 - Add fileio support for WRITE_SAME w/ UNMAP=1 discard (asias)
 - Add fileio support for UNMAP discard (asias)
 - Add tcm_vhost hotplug support to work with upstream QEMU  
   vhost-scsi-pci code (asias + mst)
 - Check for aborted sequence in tcm_fc response path (mdr)
 - Add initial iscsit_transport support into iscsi-target code (nab)
 - Refactor iscsi-target RX PDU logic + export request PDU handling  (nab)
 - Refactor iscsi-target TX queue logic + export response PDU creation (nab)
 - Add new iSCSI Extentions for RDMA (ISER) target driver (Or + nab)

The biggest changes revolve around iscsi-target refactoring in order to
support the iser-target driver.  This includes the conversion of the
iscsi-target data-path to use modern se_cmd->cmd_kref counting, and
allowing transport independent aspects of RX/TX PDU request/response
handling be shared across existing traditional iscsi-target code, and
the new iser-target code.

Thanks to Or Gerlitz + Mellanox for supporting the iser-target
development effort!

Thank you,

--nab
