Subject: [GIT PULL] target fixes for v4.12-rc4

Hello Linus,

Here are the target-pending fixes for v4.12-rc4.  Please go ahead and
pull from:

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

This includes:

  - ibmviscsis ABORT_TASK handling fixes that missed the v4.12 merge 
    window. (Bryant Ly and Michael Cyr)
  - Re-add a target-core check enforcing WRITE overflow reject that was 
    relaxed in v4.3, to avoid unsupported iscsi-target immediate data 
    overflow. (nab)
  - Fix a target-core-user OOPs during device removal. (MNC + Bryant Ly)
  - Fix a long standing iscsi-target potential issue where kthread exit 
    did not wait for kthread_should_stop(). (Jiang Yi)
  - Fix a iscsi-target v3.12.y regression OOPs involving initial login 
    PDU processing during asynchronous TCP connection close. (MNC + nab)

This is a little larger than usual for an -rc4, primarily due to the
iscsi-target v3.12.y regression OOPs bug-fix.

However, it's an important patch as MNC + Hannes where both able to
trigger it using a reduced iscsi initiator login timeout combined with a
backend taking a long time to complete I/Os during iscsi login driven
session reinstatement.

Note the trailing two patches have a recent CommitDate, as the second to
last was updated today to include MNC's tested-by and reviewed-by tags.
The patches themselves has not changed though, and both have been run
through manual and automated regression testing from multiple parties
over the last 7 days.

Thank you,

--nab
