the SCST core fails (abort task, LUN reset, ...), an SRP_RSP PDU is
now sent back to the initiator.
- Added more debug tracing statements.
- Improved readability of some parts of the source code.
- Added more comments.
- Partially reverted one hunk of r1003: while casting an unsigned 64-bit
value to the type u64 and printing such values via %llx works fine on
x86 systems, the same code triggers a compiler warning on PowerPC
systems. So while r1003 changed some (unsigned long long) casts to (u64)
casts, this revision changes these back to (unsigned long long) casts.

The following fixes were made:
- Use monotonic clock as time source instead of a real-time clock so change of system time will not affect calculation.
- Init scst_time to 0 + minor display fix.

- Added a second argument to srpt_find_channel() that specified whether or not
the channel should be removed from the channel list if found.
- Moved list_del() statement from the body of the srpt_release_channel()
function to its callers.

- Changed return type of srpt_release_channel() from int to void
because the return value did depend in a trivial way on the function
arguments. Changed the return type of srpt_find_and_release_channel()
and several of its callers also from int to void. Instead
srpt_cm_handler() now directly sets its own return value.
- Converted a list_for_each_entry_safe() into a list_for_each_entry() loop
because no elements are added or deleted in the loop body.
- Converted debug-printk() statements into TRACE_DBG().
- Changed indentation of one statement from 12 to 16 (was not reported by
checkpatch).

written into a buffer with a size of 32 bytes. Enlarged the buffer
to 36 bytes.
- Converted sprintf() calls to snprintf() calls.
- Added more TRACE_ENTRY() / TRACE_EXIT() statements.

/proc/scsi_tgt/ib_srpt/trace_level such that the behavior of the
ib_srpt target is consistent with that of other SCST drivers.

wait until srpt_refresh_port_work() finished. This race condition could be
triggered during module removal.
- Added a kernel module parameter called "trace_flag" that allows to set the
trace flags for the ib_srpt module before module initialization starts.
- Added sysfs variable /sys/class/infiniband_srpt/trace_level that allows to
display and to modify the enabled trace flags in a human-readable form.
- Added several TRACE_ENTRY() / TRACE_EXIT() statements.
- Added more comments.

- Docs updated. Particulary, a new dociment describing the SGV cache added

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.

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.

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.

- 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).
