This is a "marginal" warning, but there are only six of them in the SCST code
and this fixes two of those.
session.c:105:4: warning: cast from function call of type void * to non-matching type _Bool [-Wbad-function-cast]
target.c:668:14: warning: cast from function call of type void * to non-matching type _Bool [-Wbad-function-cast]

If this attrubute is set, each iSCSI session for this initiator has
dedicated, i.e. not shared with other sessions, pool of the iscsi{wr,rd}
kernel threads.
Useful to control per-session CPU affinity to improve performance.

Avoid that checkpatch reports the following warning:
WARNING: type 'long long unsigned' should be specified in 'unsigned long long' order.

For SCST devices with a short name determining which SCST command
threads serve a given LUN requires an (expensive) walk of the
process table. For SCST devices with a long name it is not possible
to determine unambiguously which command threads serve a given
LUN. Hence add a thread_pid sysfs attribute that makes it easy to
figure out which command threads serve a LUN.

Avoid that the checkpatch tool included in Linux kernel v3.16 reports the
following warning:
macros should not use a trailing semicolon
This patch does not change any functionality.

The lockdep_assert_held() macro is a convenient debugging tool.
However, it is inconvenient to surround each invocation of that
macro by an #ifdef/#endif pair. Hence make it easier to use this
macro with older kernel versions.

That patch contains the following changes:
* Move the code for creating a "close_sess" sysfs attribute from iscsi-scst to
the SCST core such that it becomes available for other target drivers. This
does not change the functionality of iscsi-scst.
* Add code in ib_srpt and qla2x00t to allow a session to be forcibly closed from
user space.

- SendTargets now returns all (allowed) portals. Particularly based on IET r230, 234, 249 and 264.
- Initiators assigned to security groups without LUNs will not see the target during discovery and forbidden to login to it
- Per portals access control added
- Negative sign added to wildcard matching
- Docs updated
- Cleanups and minor fixes

iSCSI-SCST: A huge improvements in errors recovery and iSCSI RFC complaince as well as performance. Also:
- Fixes and improvements for MaxOutstandingR2T>1
- Flow control tracing added.
- Cleanups
SCST core:
- Now for scst_cmd_init_stage1_done() commands preprocessing_done() is always called before xmit_response(), even in case of abort or error.
- Fixed recently introduced bug, which can lead to sending responses for aborted commands after reply on the corresponding TM command already sent.
- Flow control tracing added.
- Now it is possible to call functions setting commands execution status (e.g., scst_set_cmd_error_status()) several times for the same command. Only the first call will be completed, other calls - ignored.
- All commands are counted and shown in proc/sysfs now. Before only active, i.e. not yet executed commands, were counted and shown there.

The sysfs intarface is mostly finished. Only initiators-oriented access control not implemented and not all target drivers are updated. Only qla2x00t has been fully updated.

- iSCSI read state machine cleanups
- Fix a race when just freed iSCSI session accessed, because the corresponding SCST session is still being unregistered.

checkpatch issues reported by the checkpatch script included with the 2.6.29
kernel and that were not yet reported by the 2.6.28 checkpatch script
(trailing statements should be on the next line / struct should normally be
const).
The patch below has been tested as follows:
- Reran scripts/run-regression-tests -k 2.6.24.7 -k 2.6.25.20 -k 2.6.26.8 -k 2.6.27.21 -k 2.6.28.9 -k 2.6.29 and verified the output.
- Rebuilt, installed and loaded scst, iscsi-scst and srpt as follows:
make -s clean && make -s -C scst install && make -s -C iscsi-scst install && make -s -C srpt install && cd scstadmin && make -s && make -s install && modprobe scst_vdisk && modprobe iscsi-scst && dmesg
