aac4e05c23 Patch from Gal Rosen <galr@storwize.com>: 
I suggest the attached patch for the issue of disabling target mode
while I/O.

Fix BUG in qla target. Set ha->tgt to NULL in wrong place (when
disabling target mode). This cause to unfinished commands, and the echo
command to disabling the target mode to stuck. scst_tgt_cmd_done never
called because the ha->tgt was set to NULL before it should be. ha->tgt
already set to NULL in q2t_target_release after all task managements
finished and all commands were cleaned, so the fix just remove the set
from q2t_host_action.

7bdc38faf2 The most recent version of the sparse static source code checking tool does 
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.

e609d55773 When compiling a 2.6.30 or 2.6.30.1 kernel with the 
scst_exec_req_fifo-2.6.30.patch applied, the following warning is printed
many times by the compiler:

include/linux/scatterlist.h:223: warning: ‘enum km_type’ declared
inside parameter list
include/linux/scatterlist.h:223: warning: its scope is only this
definition or declaration, which is probably not what you want
include/linux/scatterlist.h:226: warning: ‘enum km_type’ declared
inside parameter list

The patch below fixes these compiler warnings by adding a forward declaration
for "enum km_type" in include/linux/scatterlist.h.

b780be7a7b Various improvements: 
- Display a clear warning if the user running this script does not have
  sufficient privileges to drop the VM caches.
- Made sure that header and data columns are aligned if dd reports an
  error, e.g. when trying to perform direct I/O on a device that does
  not support direct I/O.
- Made sure that header and data columns are aligned when running a
  read-only test (-r).

d29bd7bc2f Updated version of scsi_exec_async() with important fixes. Particularly: 
- A bunch of memory corruptions was fixed
 - For cases if scst_exec_req_fifo-2.6.30+.patch not applied, implementation from the patch was added to scst_lib.c. So, now for 2.6.30+ kernels scst_exec_req_fifo-2.6.X.patch is optional

7426cbb244 Only use LOAD_RISC_RAM_EXTENDED if you have to. This just might 
fix some of the 24XX and 23XX startup problems that have been
reported but are hard to predictably reproduce.

Do some minor sync with the mainline.
