7bdc38faf2 The most recent version of the sparse static source code checking tool does
now report functions that are called with a lock held but that are missing
__acquires() and __releases() annotations. The patch below adds such
annotations and makes the following sparse warnings disappear:

drivers/scst/iscsi-scst/iscsi.c:2861:9: warning: context imbalance in 'iscsi_check_send_delayed_tm_resp' - unexpected unlock
drivers/scst/iscsi-scst/nthread.c:1614:17: warning: context imbalance in 'scst_do_job_wr' - unexpected unlock
drivers/scst/iscsi-scst/iscsi.c:2861:9: warning: context imbalance in 'iscsi_check_send_delayed_tm_resp' - unexpected unlock
drivers/scst/iscsi-scst/nthread.c:1614:17: warning: context imbalance in 'scst_do_job_wr' - unexpected unlock
drivers/scst/scst_local/scst_local.c:554:30: warning: context imbalance in 'scst_local_queuecommand' - unexpected unlock

The patch below has been tested by comparing the output of
"scripts/run-regression-tests 2.6.30.3" before and after the patch was applied.

102603f46d We can't mark sess as shutting down in close_conn(), because at that time it might have pending commands. Otherwise, in case of reinstatement it might lead to data corruption, because commands in being reinstated session can be executed after commands in the new session.

bc96b052d5 The patch below adds support for the 2.6.29 kernel and also fixes the
checkpatch issues reported by the checkpatch script included with the 2.6.29
kernel and that were not yet reported by the 2.6.28 checkpatch script
(trailing statements should be on the next line / struct should normally be
const).
The patch below has been tested as follows:
- Reran scripts/run-regression-tests -k 2.6.24.7 -k 2.6.25.20 -k 2.6.26.8 -k 2.6.27.21 -k 2.6.28.9 -k 2.6.29 and verified the output.
- Rebuilt, installed and loaded scst, iscsi-scst and srpt as follows:
make -s clean && make -s -C scst install && make -s -C iscsi-scst install && make -s -C srpt install && cd scstadmin && make -s && make -s install && modprobe scst_vdisk && modprobe iscsi-scst && dmesg

d5322f10ad The patch below implements the following changes for the iSCSI-SCST HOWTO
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.

dd1400dddc 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).
