50120c37b3 scst_cmd_aborted() is a bad and ambiguous name. Rename it to scst_cmd_aborted_on_xmit() and create a new version, which truly reflects its semantic.

6e55334a9f ib_srpt: Fix QP use-after-free triggered by SRP logout. 
Fixed this by destroying cm_id before QP instead of after. The following

f2387d7956 Convert strict_strtoul() and simple_strtoul() into kstrtoul() or sscanf() 
Recent versions of the checkpatch script complain about strict_strtoul()
and simple_strtoul(), so convert calls to these functions into a call to
kstrtoul() or sscanf(). Convert loops that scan for the
next-(non-)whitespace character into a call to scst_get_next_lexem().
Make __scst_process_luns_mgmt_store() a little more strict by checking
for extraneous parameters past the last argument. Fix the value "res"
returned for the SCST_TRACE_ACTION_VALUE processing code.

From: "Paul E. McKenney" <paul.mckenney@linaro.org>

The call_rcu() in ft_tport_delete() invokes ft_tport_rcu_free(),
which just does a kfree().  So convert the call_rcu() to kfree_rcu(),
allowing ft_tport_rcu_free() to be eliminated.
