[GIT PULL] target updates for v3.20-rc1

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

Hi Linus,

Here are the target updates for v3.20-rc1 code.  Please go ahead and
pull from:

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

A heads up that you'll hit two merge conflicts as reported by SFR in
linux-next recently within drivers/vhost/scsi.c code.

The first is a conflict with a pre-merge window bug-fix in commit
46243860 that is not included in target-pending/for-next:

  vhost-scsi: Add missing virtio-scsi -> TCM attribute conversion

The resolution should be obvious for this one.

http://marc.info/?l=linux-next&m=142285892408065&w=2

The second is a conflict with Al's recent tree-wide conversion to use
copy_from_user() in commit 57dd8a073:

  vhost: vhost_scsi_handle_vq() should just use copy_from_user()

For this, please use commit 09b13fa8c included in this PULL request:

  vhost/scsi: Add ANY_LAYOUT support in vhost_scsi_handle_vq

http://marc.info/?l=linux-next&m=142346903105188&w=2

Beyond those two minor conflicts, the highlights this round include:

  - Update vhost-scsi to support F_ANY_LAYOUT using mm/iov_iter.c logic, and
    signal VERSION_1 support (MST + Viro + nab)
  - Fix iscsi/iser-target to remove problematic active_ts_set usage (Gavin Guo)
  - Update iscsi/iser-target to support multi-sequence sendtargets (Sagi)
  - Fix original PR_APTPL_BUF_LEN 8k size limitation (Martin Svec)
  - Add missing WRITE_SAME end-of-device sanity check (Bart)
  - Check for LBA + sectors wrap-around in sbc_parse_cdb() (nab)
  - Other various minor SPC/SBC compliance fixes based upon Ronnie Sahlberg
    test suite (nab)

Thank you,
