The patch below adds the following two RHEL 5 / CentOS 5 patches to the SCST
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).

The patch below is a minor correction for the 2.6.27 in-tree kernel patches
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

- 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.

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.

Recently (Subversion revision 633) code was added to scst_vdisk.c that
performs a.o. 64-bit division. While gcc supports 64-bit divisions on 32-bit
CPU's, gcc generates a function call for these 64-bit divisions (see also
http://gcc.gnu.org/onlinedocs/gccint/Integer-library-routines.html for the
entire list). Unfortunately there is no implementation available for these
functions in the Linux kernel. Which means that loading kernel modules
that contain 64-bit divisions on a 32-bit system will fail and that insmod/
modprobe will complain about undefined references to e.g. __umoddi3. AFAIK the
proper approach in the Linux kernel is to use the do_div() macro for
performing 64-bit divisions. This macro is defined in <asm/div64.h>. The patch
below converts the call to div_s64_rem() by a call to do_div().

The patch below has been verified as follows:
- Reran scripts/run-regression-tests -k 2.6.24.7 -k 2.6.25.20 -k 2.6.26.8 -k 2.6.27.12 -k 2.6.28.1
on a 64-bit system and verified that the output of the re*/sparse* files did
not contain any compilation errors.
- Verified that the patched SCST source compiles fine on CentOS 5.2, 32-bit.
- Verified that the scst_vdisk module loads correctly on CentOS 5.2, 32-bit.
