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.

source tree:
- Support for zero-copy TCP transfer completion.
- An implementation of scsi_execute_async_fifo().
Except for the hunk headers, these patches are identical to similarly named
patches already present in the SCST source tree.
Additionally, implementations of seq_list_start() and seq_list_next() are
provided for those kernel versions that do not define these functions.
The patch below has been tested by verifying that iSCSI data transfer still
works OK on CentOS 5.2 (x86_64).

I submitted about three months ago: the patch headers now refer to the 2.6.27
kernel as they should instead of the 2.6.26 kernel. At least one user has been
confused by this. The patch below does not change any behavior of SCST.
The patch has been tested by verifying that the output of the following
command remained the same as before the modifications:
scripts/run-regression-tests -k 2.6.27

- Introduce min*/max*() and more list_* macros
- Multipart PDU support for discovery sessions
The conn's response buffer is now replaced with a list of buffers and
all users are updated accordingly. Discovery sessions can make use of
this mechanism, if the list of targets + addresses does not fit into a
single text PDU, the initiator may now retrieve subsequent parts.
This also fixes the data segment handling for discovery sessions.

- Update MaxConnections documentation
- Remove isns config description from man page
- Check return values of chdir(), ftruncate() and write(), because recent versions of the glibc insist on the return value being checked by
introducing __attribute__((warn_unused_result)) to these functions.
- Fix snprintf use in isns.c
- Take \0-termination into account when passing strings to isns_tlv_set() to solve incompatibility with MS iSNS 3.0 as IQN length is multiple of 4
- Fix list corruption if SCST target registration fails
- Register the target port actually used instead of the default iSCSI port.
- Remove unused connection->pad
- Refactor cmnd_execute()

Subject: [Patch 1/1] Segfault in ietd buffer overrun in dump_line
Fix a buffer overrun problem in __dump_line function in log.c file.
It also removes a stray 'return' call in log_pdu function which was
restricting a PDU dump call to complete log_pdu operation.
Also, in log_pdu function, the first check for log_level against
passed parameter for log was incorrect and would have forced a return
even when the caller has set the logging level to acceptable level.

the most recent versions (checkpatch 2.6.28 / latest sparse git version) and
that were not reported by previous versions (checkpatch 2.6.27 / sparse 0.4.1).
The patch below fixes the following issues:
* Removed trailing space in iscsi-scst/README_in-tree.
* Fixed sparse complaints about functions that were not declared static.
* Fixed sparse complaints about casts between address spaces: such casts are
now either fixed or explicit (via the __force keyword).
The patch below has been verified by checking the output produced by:

Apparently not all messages reported by this version are correct. So I switched
back to the last released sparse version (0.4.1). The patch below fixes all

below most lines that were too long have been split, but some code has also
been moved into helper functions in order to keep the code readable. No
functionality has been changed.

- Verified that the iSCSI target kernel module still loads.
- Verified the output generated by scripts/run-regression-tests -k 2.6.27.5.

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.
