sense, replaced this expression by "sizeof(*sense)" and a BUILD_BUG_ON()
statement that verifies that sizeof(*sense) is a multiple of four. Should
the first expression have been "roundup(sizeof(*sense), 4)" ?

ib_dma_sync_for_cpu() calls do now only synchronize the data areas used.
- Removed per-command mutex again because it's not a full solution with
regard to avoiding races between module unloading / IB error handling and
SCST's command handling.

code.
- Fixed the bug that new commands could be queued for a channel that was
being closed.
- Bug fix: ib_dma_unmap_sg() is now called by srpt_xmit_response() when
aborting commands.
- Changed default value of the kernel module parameter 'thread' from zero
to one because using thread=0 can cause the Linux and the OFED SRP
initiator to lock up -- see also
http://bugzilla.kernel.org/show_bug.cgi?id=14235 and
https://bugs.openfabrics.org/show_bug.cgi?id=1745.
- Made disconnect logging more detailed -- added cm_id in output.
- Changed argument type of second argument of srpt_release_channel() from
int to bool.
- Eliminated srpt_abort_scst_cmd's 'tell_initiator' argument because this
argument always has the same value (i.e. true).
- Simplified abortion of commands in state SRPT_STATE_NEW. Simplified
implementation of srpt_on_free_cmd().

As a result, the maximum number of sg list elements that an initiator
can pass in one message increased from 58 to 251.
- Added kernel module parameter srp_max_message_size, which allows to
specify the maximum size of SRP control messages.

- Introduced new kernel module parameter srp_max_rdma_size. This parameter
allows to configure the maximum size of SRP RDMA transfers.

- Inserted tests such that ib_dma_unmap_sg() is never called with a NULL
second argument.
- Fixed race conditions triggered by ioctx->state manipulations.

SRPT_STATE_NEW are now aborted properly too. Until now aborting an
SCST command that had state SRPT_STATE_NEW triggered a sBUG_ON()
statement in scst_tgt_cmd_done().

allows to control by how much the srpt_completion() function (which runs
in interrupt context) will be delayed.

a command that has already been aborted, changed the message that
reports this from an error message to an informational message.

replaced dma_*map* calls by ib_dma_*map* calls. Added the conversion
of dma_sync_single_for_device() to ib_dma_sync_single_for_device().
This only changes the behavior of SRPT for those IB interfaces whose
driver implements the ib_dma_mapping_ops operations.

The OFED commit made a.o. ib_srpt.c compile on 2.6.30 and later kernels.
Although the SCST ib_srpt.c code already compiles on a 2.6.30 kernel, this
commit has been ported to SCST because the source code of the OFED
implementation is cleaner. This commit does not change any functionality
of SCST's SRPT.

PRINT_INFO() and related macro's.
- Replaced printk(KERN_INFO PFX and printk(KERN_ERROR PFX by
PRINT_INFO( and PRINT_ERROR( respectively.

"Mellanox OFED SRP target" to "SCST SRP target" to reflect that this
version of the SRP target is distributed through the SCST project.
- Added kernel parameter use_port_guid_in_session_name that allows to
use the original session naming scheme of the SRP target. This should
make it again possible to connect to a multiport SRP target by masking
out redundant paths on the target.
- Made sure that whenever a login is rejected that a kernel message is
generated (printk()) such that this information ends up in
/var/log/messages.

solve the connectivity problem between WinOF and an SRP target
equipped with multiple IB ports.

parameter to true should make it possible to connect from a WinOF
initiator to an SRP target when there is more than one IB path
between initiator and target.
- Renamed mellanox_ioc_guid into global_ioc_guid.
