c3351dfabf Merge branch 'for-next' of git://git.kernel.org/pub/scm/linux/kernel/git/nab/target-pending
Pull SCSI target updates from Nicholas Bellinger:
 "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.

  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"

f4c24db1b7 qla_target: don't delete changed nacls
The code is currently riddled with "drop the hardware_lock to avoid a
deadlock" bugs that expose races.  One of those races seems to expose a
valid warning in tcm_qla2xxx_clear_nacl_from_fcport_map.  Add some
bandaid to it.

f9b6721a9c qla_target: improve qlt_unmap_sg()
Remove the inline attribute.  Modern compilers ignore it and the
function has grown beyond where inline made sense anyway.
Remove the BUG_ON(!cmd->sg_mapped), and instead return if sg_mapped is
not set.  Every caller is doing this check, so we might as well have it
in one place instead of four.

33e7997755 qla2xxx: Add support for QFull throttling and Term Exchange retry
Through the qla target code, the qlt_send_term_exchange() routine
is used in various different places to cleanup an exchange. For the
case of IOCB request queue is full, the exchange is left unhandled/
dangling. Existing code does not have re-try logic to cleanup the
exchange. This patch add retry logic to cleanup the exchange before
letting new commands through.

For the case of FW running out of exchanges, driver need to reply
SAM_STAT_BUSY to the initiators. This patch add a pending queue
for the busy reply in case IOCB queue is unable to handle the cmd.
