I suggest the attached patch for the issue of disabling target mode
while I/O.
Fix BUG in qla target. Set ha->tgt to NULL in wrong place (when
disabling target mode). This cause to unfinished commands, and the echo
command to disabling the target mode to stuck. scst_tgt_cmd_done never
called because the ha->tgt was set to NULL before it should be. ha->tgt
already set to NULL in q2t_target_release after all task managements
finished and all commands were cleaned, so the fix just remove the set
from q2t_host_action.

While writing DKMS support for the SCST and iSCST-SCST kernel modules, I ran
into a (common) problem with regard to out-of-tree build detection. A common
method to detect out-of-tree building is by using the KERNELRELEASE variable.
The usage of this variable poses a problem when using DKMS. DKMS itself uses
the KERNELRELEASE variable to specify the kernel for which the driver to
build. A suggested alternative would to use the PATCHLEVEL variable as part
of the detection mechanism instead. I attached a patch reflecting this
suggested change.

There are 16 characters of the port_name + 7 characters of ":" + "\0" of
sprintf = total 24 bytes.
wwn_str has only 16 bytes.

document:
- Added RHEL / CentOS to the list of officially supported kernels.
- Mentioned that regenerating the initial RAM disk is an explicit step on many
distro's.
- Replaced shell instructions for generating /etc/scst.conf by a sequence of
scstadmin commands.
- Added note about insserv.
Also it adds small HOWTO how to recompile RHEL/CentOS kernel in README_RHEL.
Also it implements some docs cleanups.

WARNING! This commit changes external SCST interface, so it can break compilation of your out of SCST SVN tree target driver or dev handler. To fix it, simply supply the preferred exection context to scst_cmd_done() and/or scst_tgt_cmd_done().
Thanks to Bart Van Assche <bart.vanassche@gmail.com> for pointing on it.

This patch has been tested by verifying that the SCST sources still compile
fine (make -s clean && make -C srpt -s clean && make -s scst iscsi-scst && make -C srpt -s).

an external module. When applying the SCST kernel patch to the mainstream
kernel tree with debugging and/or tracing enabled however, the resulting code
triggers a compiler error. This is because the symbols DEBUG and TRACING
conflict with symbols with the same named defined in unrelated kernel headers.
The patch below resolves these conflicts by renaming the following preprocessor
symbols:
- DEBUG into CONFIG_SCST_DEBUG.
- DEBUG_DIGEST_FAILURES into CONFIG_SCST_ISCSI_DEBUG_DIGEST_FAILURES.
- DEBUG_OOM into CONFIG_SCST_DEBUG_OOM.
- DEBUG_RETRY into CONFIG_SCST_DEBUG_RETRY.
- DEBUG_SN into CONFIG_SCST_DEBUG_SN.
- DEBUG_TM into CONFIG_SCST_DEBUG_TM.
- EXTRACHECKS into CONFIG_SCST_EXTRACHECKS.
- SCST_HIGHMEM into CONFIG_SCST_HIGHMEM.
- STRICT_SERIALIZING into CONFIG_SCST_STRICT_SERIALIZING.
- TM_DBG_GO_OFFLINE into CONFIG_SCST_TM_DBG_GO_OFFLINE. Mapped 0/1 values
into macro undefined / macro defined.
- TRACING into CONFIG_SCST_TRACING.
- USE_EXPECTED_VALUES into CONFIG_SCST_USE_EXPECTED_VALUES.
- In qla_isp/linux/isp_scst.c, renamed DEBUG into DEBUG_ISP_SCST.
- In qla_isp/..., renamed SCSI_TARGET in SCST_SCSI_TARGET.
- In qla_isp/..., renamed SCSI_TARGET_DEV in SCST_SCSI_TARGET_DEV.
Additionally, all CONFIG_SCSI_TARGET* macro's are renamed into CONFIG_SCST* in
order to avoid confusion between the STGT CONFIG-symbols and the SCST CONFIG-
symbols.
The following additional options are now configurable through Kconfig:
- CONFIG_SCST_ISCSI_DEBUG_DIGEST_FAILURES
- CONFIG_SCST_STRICT_SERIALIZING
- CONFIG_SCST_STRICT_SECURITY
- CONFIG_SCST_ALLOW_PASSTHROUGH_IO_SUBMIT_IN_SIRQ
- CONFIG_SCST_ABORT_CONSIDER_FINISHED_TASKS_AS_NOT_EXISTING
- CONFIG_SCST_USE_EXPECTED_VALUES
- CONFIG_SCST_DEBUG_OOM
- CONFIG_SCST_DEBUG_RETRY
- CONFIG_SCST_DEBUG_SN
- CONFIG_SCST_DEBUG_TM
- CONFIG_SCST_TM_DBG_GO_OFFLINE
The patch below has been verified as follows:
- Verified that the following command does not print any new warning messages:
make -s clean && make -C srpt -s clean && make -s scst iscsi-scst && make -C srpt -s
- Verified as follows that the internal SCST patches still apply cleanly:
for p in *patch; do patch -p0 --dry-run -f -s <$p; done
- Checked that the patch generated by generate-kernel-patch still applies
cleanly to the 2.6.25.7 kernel, and that the patched kernel tree still
compiles, installs and boots fine, that the iscsi-scst, ib_srpt,
scst_disk and scst_vdisk modules still load, and that iSCSI communication
still works fine. All SCST kernel configuration options that could be
enabled have been enabled during this test.
