[GIT PULL] target updates for v3.18-rc2

Hi Linus,
Here are the target updates for v3.18-rc2 code. These where originally
destined for -rc1, but due to the combination of travel last week for
KVM Forum and my mistake of taking the three week merge window
literally, the pull request slipped.. Apologies for that.
A heads-up that you'll hit one minor conflict with scsi.git, that was
caught by sfr in linux-next here:
http://marc.info/?l=linux-next&m=141223868207635&w=2
Please go ahead and pull from:
git://git.kernel.org/pub/scm/linux/kernel/git/nab/target-pending.git for-next
Things where reasonably quiet this round. The highlights include:
- New userspace backend driver (target_core_user.ko) by Shaohua Li
and Andy Grover
- A number of cleanups in target, iscsi-taret and qla_target code
from Joern Engel
- Fix an OOPs related to queue full handling with CHECK_CONDITION
status from Quinn Tran
- Fix to disable TX completion interrupt coalescing in iser-target,
that was causing problems on some hardware
- Fix for PR APTPL metadata handling with demo-mode ACLs
I'm most excited about the new backend driver that uses UIO + shared
memory ring to dispatch I/O and control commands into user-space. This
was probably the most requested feature by users over the last couple of
years, and opens up a new area of development + porting of existing
user-space storage applications to LIO. Thanks to Shaohua + Andy for
making this happen.
Also another honorable mention, a new Xen PV SCSI driver was merged via
the xen/tip.git tree recently, which puts us now at 10 target drivers in
upstream! Thanks to David Vrabel + Juergen Gross for their work to get
this code merged.
Thank you,
