- 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.

srpt_release_channel_by_cmid().
- Removed tracing statements from srpt_unmap_sg_to_ib_sge() because this
function is now invoked while performing I/O.

- Fixed system lockup triggered by "rmmod ib_srpt" while the SRP was writing
data. This lockup occurred because srpt_reset_ioctx() was not resetting
the pointers to the memory it freed, which indirectly triggered a kernel
oops in the IB interrupt handler.
- Fixed BUG() during "rmmod ib_srpt" triggered by calling scst_rx_cmd()
after scst_unregister_session(). This has been fixed by making sure that
the channel state is set to RDMA_CHANNEL_DISCONNECTING before calling
scst_unregister_session().
Performance improvements:
- Simplified cmd_wait_list manipulation code.

- Fixed races on srpt_ioctx::state manipulation by declaring this variable
atomic.
- Fixed races on srpt_rdma_ch::state manipulation by declaring this variable
atomic.
- Fixed bug in srpt_abort_scst_cmd(): SRPT_STATE_DATA_IN was not yet handled.
- Fixed races on srpt_rdma_ch::cm_id destruction. Clearly documented which
object owns the cm_id at which time.
Performance improvements:
- Eliminated the list of active commands (active_scmnd_list) because this
list was a duplicated of a list already kept by the SCST core.
- Switched to double-checked locking in srpt_handle_new_iu(). This saves one
spin_lock_irqsave() and one spin_unlock_irqrestore() call in the common
case (that is, a live channel).
- Eliminated RDMA channel state tests in SCST command handling callback
functions -- removed the function srpt_abort_if_disconnecting().

- The message that sense data is truncated is now generated via the
PRINT_WARNING() macro instead of TRACE_DBG().
- Cleaned up code for sense data truncation.
- Compiles again on RHEL and CentOS systems.

- Fixes Some code error in comparison.html
- Add class tab to Orange.css
- Add tab class in code inside Contributing.html

the per-channel queue pair. This counter is used to prevent that
ib_post_send() triggers a queue overflow.
- Fixed error handling in srpt_xfer_data(): srpt_unmap_sg_to_ib_sge() is now
called before returning an error code.
- Simplified implementation of the sysfs attribute login_info.
