[GIT PULL] target updates for v4.5-rc1

[Nicholas A. Bellinger]

Hello Linus,

Here are target-pending updates for v4.5-rc1 code.

Please go ahead and PULL from:

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

Note that Sagi + Jenny's series for iser target + initiator remote
invalidation is being merged via rdma.git, and Doug will be sending
in his rmda.git PULL request.

As per SFR, you'll (eventually) hit a minor iser-target merge conflict
vs. rdma.git once you PULL from Doug due to a ERR_PTR bug-fix:

http://marc.info/?l=linux-next&m=145222770105861&w=2

The highlights this round include:

 - Introduce configfs support for unlocked configfs_depend_item()
   (krzysztof + andrezej)
 - Conversion of usb-gadget target driver to new function registration 
   interface (andrzej + sebastian)
 - Enable qla2xxx FC target mode support for Extended Logins
   (himansu + giridhar)
 - Enable qla2xxx FC target mode support for Exchange Offload
   (himansu + giridhar)
 - Add qla2xxx FC target mode irq affinity notification +
   selective command queuing.  (quinn + himanshu)
 - Fix iscsi-target deadlock in se_node_acl configfs deletion
   (sagi + nab)
 - Convert se_node_acl configfs deletion + se_node_acl->queue_depth
   to proper se_session->sess_kref + target_get_session() usage.
   (hch + sagi + nab)
 - Fix long-standing race between se_node_acl->acl_kref get and
   get_initiator_node_acl() lookup.  (hch + nab)
 - Fix target/user block-size handling, and make sure netlink reaches
   all network namespaces (sheng + andy)

Note there is an outstanding bug-fix series for remote I_T nexus port
TMR LUN_RESET has been posted and still being tested, and will likely
become post -rc1 material at this point.

Thank you,

--nab
