* For some Linux distro's the command iscsi-iname is installed in /usr/sbin
and for others in /sbin.
* The scst and scst_vdisk modules must be loaded before the sample scstadmin
commands work.

function scst_sysfs_cleanup() is declared as an exit-only function while it is
also called from init_scst(). The patch below fixes this section mismatch.
This patch has been tested by verifying that the following command does not
report any section mismatches:
make CONFIG_DEBUG_SECTION_MISMATCH=y scst iscsi-scst srpt

- Convert sense data to/from fixed format / descriptor format before
sending back a response.
- Print an error message to the kernel log when an unsupported IB event
has been received.
- Return the SCSI status BUSY instead of CHECK CONDITION when allocating
an SCST command failed (until r1409, the SCSI status in the SRP_RSP
information unit was set to TASK SET FULL in this case).

- Fixed: the SCSOLNT and UCSOLNT bits were ignored in received SRP requests,
and the SOLNT bit was not set in responses when required. This is required
by the SRP protocol specification.
- Fixed: SRP_RSP messages must be limited to the MAXIMUM TARGET TO INITIATOR
IU LENGTH field indicated in the SRP_LOGIN_RSP response instead of the
maximum message size supported by SRPT. This is also required by the SRP
protocol specification.
- Fixed: the STATUS field of response messages with status GOOD and that
contain sense data is no longer modified into CHECK CONDITION.
Internal changes (refactoring):
- Replaced the SCSI sense data handling data structures and code in SRPT by
those of the SCST core.
- Moved the code for building an error response from srpt_handle_cmd() and
srpt_handle_tsk_mgmt() to srpt_handle_new_iu().
- Removed the ioctx::data_len member.

- Made sure that the SRPT source code compiles again on systems with a 2.6.29
or older kernel.

descriptors are now reported by returning -EINVAL instead of setting the
third argument to true. Removed the third argument of this function.
- Added support for SRP_CMD requests with non-zero ADDITIONAL CDB LENGTH.
Note: support for these requests has not yet been tested -- I do not know
of any SRP initiator that generates such requests.

- Changed default value of srp_max_message_size from 4096 to 2116. This
size corresponds to the size of an SRP_CMD request message containing
an indirect buffer list with 128 elements.
- A warning is now printed when an SRP_CMD request is received containing
more than one CDB -- this kind of messages is not yet supported.
- Switched back from multiple ib_dma_sync_single_for_cpu() calls to a
single call because the latter results in better performance.
- An error message is now printed if a corrupt SRP_CMD request has been
received. Before these were ignored silently.

- Removed a spinlock that became superfluous.
- Fixed checkpatch and sparse complaints.
