[GIT PULL] target updates for v4.3-rc1

["Nicholas A. Bellinger" <nab@linux-iscsi.org>]

(RESENDING)

Hi Linus.

Here are the outstanding target-pending updates for v4.3-rc1 code.
Please go ahead and PULL from:

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

There are two small conflicts noted by SFR due to a revert in libata.git
code:

http://marc.info/?l=linux-kernel&m=143865933819312&w=2
http://marc.info/?l=linux-kernel&m=143865935919329&w=2

The resolution should be self explanatory.

Mostly bug-fixes and minor changes this round.  The fallout from the big
v4.2-rc1 RCU conversion have (thus far) been minimal.

The highlights this round include:

  - Move sense handling routines into scsi_common code (Sagi)
  - Return ABORTED_COMMAND sense key for PI errors (Sagi)
  - Add tpg_enabled_sendtargets attribute for disabled iscsi-target discovery (David)
  - Shrink target struct se_cmd by rearranging fields (Roland)
  - Drop iSCSI use of mutex around max_cmd_sn increment (Roland)
  - Replace iSCSI __kernel_sockaddr_storage with sockaddr_storage (Andy + Chris)
  - Honor fabric max_data_sg_nents I/O transfer limit (Arun + Himanshu + nab)
  - Fix EXTENDED_COPY >= v4.1 regression OOPsen (Alex + nab)

Thank you,
