Replace scnprintf() with sysfs_emit() and sysfs_emit_at() in sysfs show handlers.
These helper functions are specifically designed for sysfs output, providing safer
handling of buffer lengths and consistency across kernel sysfs interfaces.
This patch does not change any functionality.
Replace all uses of sprintf() with scnprintf() in sysfs attribute
callbacks to eliminate the risk of buffer overflows.
This patch does not change any functionality.
Suppress several Coverity "tainted scalar" complaints and also two other
false positive Coverity complaints.

Since all RHEL/CentOS 5 users have upgraded to a newer version, procfs
support is no longer necessary. Hence remove procfs support. This patch
has been generated as follows:
git grep -lw CONFIG_SCST_PROC iscsi-scst qla2x00t scst scst_local srpt |\
while read f; do
echo ${f}
unifdef -U CONFIG_SCST_PROC ${f} >${f}.out
mv ${f}.out ${f}
done
followed by two small manual edits in scst/include/scst.h and also in
qla2x00t/qla2x00-target/qla2x00t.c.

Change local names of ioctl() and open() to not conflict with C library names.
This isn't really a bug in a strictly kernel-resident build, but the change
avoids symbol conflicts with libc when building for usermode.

The T10-PI patch (r6162) increases the time needed to run mkfs.ext4
over iSCSI from less than a second to several minutes. This is a
regression so revert the T10-PI patch until there is sufficient time
to find the root cause of this regression and to fix this regression.

Avoid that checkpatch reports the following warning:
WARNING: type 'long long unsigned' should be specified in 'unsigned long long' order.

The lockdep_assert_held() macro is a convenient debugging tool.
However, it is inconvenient to surround each invocation of that
macro by an #ifdef/#endif pair. Hence make it easier to use this
macro with older kernel versions.

The following procfs-related changes have been included in kernel 3.10:
- The PDE() macro has been removed from <linux/proc_fs.h>.
- The create_proc_entry() function has been removed.
- The proc_info field has been removed from struct scsi_host_template.
Unbreak the procfs build for kernel versions >= 3.10

- SendTargets now returns all (allowed) portals. Particularly based on IET r230, 234, 249 and 264.
- Initiators assigned to security groups without LUNs will not see the target during discovery and forbidden to login to it
- Per portals access control added
- Negative sign added to wildcard matching
- Docs updated
- Cleanups and minor fixes

iSCSI-SCST: A huge improvements in errors recovery and iSCSI RFC complaince as well as performance. Also:
- Fixes and improvements for MaxOutstandingR2T>1
- Flow control tracing added.
- Cleanups
SCST core:
- Now for scst_cmd_init_stage1_done() commands preprocessing_done() is always called before xmit_response(), even in case of abort or error.
- Fixed recently introduced bug, which can lead to sending responses for aborted commands after reply on the corresponding TM command already sent.
- Flow control tracing added.
- Now it is possible to call functions setting commands execution status (e.g., scst_set_cmd_error_status()) several times for the same command. Only the first call will be completed, other calls - ignored.
- All commands are counted and shown in proc/sysfs now. Before only active, i.e. not yet executed commands, were counted and shown there.
