Subject: [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:

Please go ahead and pull from:

   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,
