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.

now report functions that are called with a lock held but that are missing
__acquires() and __releases() annotations. The patch below adds such
annotations and makes the following sparse warnings disappear:
drivers/scst/iscsi-scst/iscsi.c:2861:9: warning: context imbalance in 'iscsi_check_send_delayed_tm_resp' - unexpected unlock
drivers/scst/iscsi-scst/nthread.c:1614:17: warning: context imbalance in 'scst_do_job_wr' - unexpected unlock
drivers/scst/iscsi-scst/iscsi.c:2861:9: warning: context imbalance in 'iscsi_check_send_delayed_tm_resp' - unexpected unlock
drivers/scst/iscsi-scst/nthread.c:1614:17: warning: context imbalance in 'scst_do_job_wr' - unexpected unlock
drivers/scst/scst_local/scst_local.c:554:30: warning: context imbalance in 'scst_local_queuecommand' - unexpected unlock
The patch below has been tested by comparing the output of
"scripts/run-regression-tests 2.6.30.3" before and after the patch was applied.

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
