5b77c89fbd Patch from Gilad H <gilad.public2@gmail.com> with improvements fixing the following scenario: 
1. Commands start going to the init_cmd_list probably because SCST was suspended
2. A command is now waiting in the init_cmd_list, it was not yet completely initialized (more impotently cmd->dev == NULL)
3. A clear task set for the same lun arrives from a different initiator
4. The command is marked as aborted from other initiator and released from the init list.
5. The command gets to the PRE_XMIT_RESPONSE state, since it was aborted the scst_xmit_process_aborted_cmd is called.
6. At this stage since the command is marked as aborted by other initiator the scst checks for the device TAS flag (cmd->dev->tas) however cmd->dev is NULL and we crash on Null pointer de-referencing.

23accb2e12 When converting the SCST source code into a series of upstream patches, SCST 
is built via the kbuild infastructure. In kernel version 2.6.24 (commit
f77bf01425b11947eeb3b5b54685212c302741b8) the kbuild variable ccflags-y has
been introduced and the use of EXTRA_CFLAGS in kbuild makefiles has been
deprecated. The patch below converts SCST's in-tree makefiles such that these
use ccflags-y instead of EXTRA_CFLAGS when generating kernel patches for
kernel 2.6.24 or later.

Additionally, this patch removes the "default n" from the file
scst/kernel/in-tree/Kconfig.scst since this statement is superfluous.

The patch below has been tested by verifying the output of the following
command:
for ((v=23;v<=32;v++)); do rm -rf re* && scripts/run-regression-tests 2.6.$v; done

5cc522712e Fixed the following race conditions: 
- With thread=1, the kernel thread was stopped before all I/O was stopped.
  This could result in IB completions for responses sent to the initiator
  not being processed, scst_tgt_cmd_done() not being called for certain
  SCST commands and hence this race could cause "rmmod ib_srpt" to hang.
- ib_unregister_event_handler() was called after cancel_work_sync(). This
  could cause srpt_event_handler() to queue new work, work that could be
  executed after the data it operates on had been deallocated.
Change: simplified module unloading by calling ib_destroy_cm_id(sdev->cm_id)
  before calling scst_unregister(). This made the variable "cleaning_up"
  superfluous.
