16a955ab7b scst: Move vfs_fsync() backports to a new header file 
This patch does not change any functionality but makes the SCST
source code easier to read. The intention is later on to move all
backported functions and macros from <scst.h> into <backport.h>.

628f3939bc scst: Rework SCSI pass-through support for kernel versions >= 2.6.30 
Changes in this patch:
- Rework the SCSI pass-through code such that for kernel versions
  >= 2.6.30 the scst_exec_req_fifo patch is no longer needed.
- Modify the pass-through code such that blk_rq_append_bio() is only
  called for kernel version 2.6.30. For later kernel versions
  blk_make_request() is called instead.
- Rework scst_scsi_exec_async().
- Add debug tracing of SCSI pass-through result status.
- Add a lockdep_assert_held() call in scsi_end_async().

e1447ae241 Add implicit ALUA support. On a setup with more than one target port 
(sometimes called storage head) this patch makes it possible to tell the
initiator which port to use. Since that information can be specified per LUN,
with this patch it is not only possible to tell the initiator which path to
choose but also to balance the load over target ports. Target port attributes
can not only be defined for target ports that exist on the system on which
SCST is running but also for target ports present on other nodes of the same
HA setup. As far as I know this feature is unique among open source storage
target implementations.

Note: with this patch SCSI target port attributes can be defined for each LUN
defined on each SCST target individually. Such an SCST target is either a
physical entity (e.g. a HCA for the ib_srpt driver) or a logical entity (e.g.
an iSCSI target for the iscsi_scst driver). In the last case it is up to the
user to make sure that there is a one-to-one relationship between SCST target
and SCSI target port.

This patch is based on the specifications in the ANSI T10 spc4r30 document.
