- Zero-copy feature, introduced by put_page_callback patch, made kernel compile time configurable via CONFIG_TCP_ZERO_COPY_TRANSFER_COMPLETION_NOTIFICATION option. If you upgrade from earlier versions, see the corresponding "[CAUTION]" e-mail in scst-devel mailing list about possible compatibility problems.
- SRP target temporary removed from "all" and "install" the main Makefile targets, since it isn't compiled on 2.6.26
- Minor fixes and cleanups

One more optional fix (that i didn't do) is instead of casting
arg in the ioctl() function before every call to function
is to do the casting only once to a temporary variable and
send this variable to every function.

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.

- The script specialize-patch now acts as if #define INSIDE_KERNEL_TREE 1
is effective.
- The script generate-kernel-patch now renames sBUG_ON() into BUG_ON()
and sBUG() into BUG(). The same script removes the definitions of the
sBUG_ON(), sBUG() and WARN_ON_ONCE() macro's from the header file
scst_debug.h. The last macro is only removed for kernel versions later than
2.6.19.
This patch has been tested as follows:
- Compared the output of the command "scripts/generate-kernel-patch 2.6.25"
before and after the changes.
- Verified the newly generated patch with checkpatch. Checkpatch statistics
are now as follows:
521 WARNING: line over 80 characters
12 WARNING: consider using strict_strtoul in preference to simple_strtoul
10 WARNING: printk() should include KERN_ facility level
3 WARNING: CVS style keyword markers, these will _not_ be updated
2 WARNING: do not add new typedefs
1 WARNING: Use of volatile is usually wrong: see Documentation/volatile-considered-harmful.txt
- Verified that the generated kernel patch still applies cleanly to the
2.6.25.10 kernel and that this kernel still compiles, installs and boots fine.

- Substituted lun_t by uint64_t and removed typedef lun_t.

make -s clean && make -C srpt -s clean && make -s scst iscsi-scst && make -C srpt -s
- Checked that the patch generated by generate-kernel-patch still applies

- Verified that checkpatch does not report any new warnings or errors.
