- 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()
- Version changed

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.

immediately after the lock is released and we should catch it.
- Text in README about barriers usage updated
- Minor cleanup with aim to have more robust code

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:
scripts/run-regression-tests -k 2.6.28.1

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.

It, hopefully, fixes compilation problems on CentOS 5.2 as well as on vanilla kernels <2.6.28

- In scst_local new experimental compile-time option to force direct processing added
- Attempt in SCST structures to separate read-mostly from read-write data to decrease cache ping-pong between CPUs
- In scst_vdisk new module parameter num_threads added to specify a number of threads for each vdisk/vcdrom. Default is 5.
- Debug logging for failed digests in iSCSI-SCST improved
- Docs updates/cleanups

int returns and not boolean.
