[PATCH 0/3] target: Fixes for v4.12-rc1

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

From: Nicholas Bellinger <nab@linux-iscsi.org>

Hi all,

Here are a couple of fixes from the last weeks testing while
continuing longevity and scale out workloads on v4.x target code.

This series contains three patches.  The first is to address
a COMPARE_AND_WRITE se_cmd reference leak where the READ phase
hits a non GOOD status, observed with ESX VAAI hosts when
outstanding READ I/O reaches a point where non SAM_STAT_GOOD
status completions start to happen.

The second addresses a hung task bug observed with iscsi-target
ports while explicitly changing the active per se_node_acl
queue_depth via the existing configfs attribute, if a new iscsi
login was already forcing session reinstatement.

And the third to is avoid forcing an session reinstatement if
queue_depth is changed via configfs, but the value itself has
not changed.

The series has been verified on v4.1.y by DATERA Q/A and
automation teams.

Thank you,

--nab
