I had some problems compiling scst due to some bashisms in the Makefiles. As
you will know, Debian uses /bin/dash as default shell and /bin/sh is only a

the better solution) use SHELL=/bin/bash in the Makefile.
I have made a patch for the Makefiles in question (I hope, that are all

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.

Fixed the following race conditions:

  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)

A huge chunk of related to each other changes, which had to be tested together.

iSCSI-SCST: A huge improvements in errors recovery and iSCSI RFC complaince as well as performance. Also:

 - Fixes and improvements for MaxOutstandingR2T>1

 - Flow control tracing added.

 - Cleanups

SCST core:

 - Now for scst_cmd_init_stage1_done() commands preprocessing_done() is always called before xmit_response(), even in case of abort or error.

 - Fixed recently introduced bug, which can lead to sending responses for aborted commands after reply on the corresponding TM command already sent.

 - Flow control tracing added.

 - Now it is possible to call functions setting commands execution status (e.g., scst_set_cmd_error_status()) several times for the same command. Only the first call will be completed, other calls - ignored.

 - All commands are counted and shown in proc/sysfs now. Before only active, i.e. not yet executed commands, were counted and shown there.
