Subject: [GIT PULL] target fixes for v3.6-rc3

Hello Linus!

The following are pending target fixes destined for v3.6-rc3.  Please go
ahead and pull from:

  git://git.kernel.org/pub/scm/linux/kernel/git/nab/target-pending.git master

The executive summary includes:

- Post-merge review comments for tcm_vhost (MST + nab)
- Avoid debugging overhead when not debugging for tcm-fc(FCoE) (MDR)
- Fix NULL pointer dereference bug on alloc_page failulre (Yi Zou)
- Fix REPORT_LUNs regression bug with pSCSI export (AlexE + nab)
- Fix regression bug with handling of zero-length data CDBs (nab)
- Fix vhost_scsi_target structure alignment (MST)

Thanks again to everyone who contributed a bugfix patch, gave review
feedback on tcm_vhost code, and/or reported a bug during their own
testing over the last weeks.

There is one other outstanding bug reported by Roland recently related
to SCSI transfer length overflow handling, for which the current
proposed bugfix has been left in queue pending further testing with
other non iscsi-target based fabric drivers.

As the patch is verified with loopback (local SGL memory from SCSI LLD)
+ tcm_qla2xxx (TCM allocated SGL memory mapped to PCI HW) fabric ports,
it will be included into the next 3.6-rc-fixes PULL request.

Thank you!
