Subject: [GIT PULL] target updates for v4.16-rc1

Hi Linus,

Here are the target-pending updates for v4.16-rc1.  Please go ahead and
pull from:

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

The highlights include:

- Numerous target-core-user improvements related to queue full and timeout handling. (MNC)
- Prevent target-core-user corruption when invalid data page is requested. (MNC)
- Add target-core device action configfs attributes to allow user-space to
  trigger events separate from existing attributes exposed to end-users. (MNC)
- Fix iscsi-target NULL pointer dereference 4.6+ regression in CHAP error path.
  (David Disseldorp)
- Avoid target-core backend UNMAP callbacks if range is zero. (Andrei Vagin)
- Fix a iscsi-target 4.14+ regression related multiple PDU logins, that
  was exposed due to removal of TCP prequeue support. (Florian Westphal + MNC)

Also, there is a iser-target bug still being worked on for post -rc1
code to address a long standing issue resulting in persistent
ib_post_send() failures, for RNICs with small max_send_sge.  

Thank you,

--nab
