iscsi-scst: One major number per thread pool
Assign one major number per thread pool instead of as many major
numbers as there are threads in a thread pool. Do not increment
'major' if thread pool allocation fails. Micro-optimize
iscsi_threads_pool_get() by eliminating the assignment to 'fn'
and the write via snprintf() into name[].

scst_main: Fix race between scst_resume_activity() and scst_init_thread()
After SCST_FLAG_SUSPENDED has been cleared it is essential that
scst_do_job_init() reexamines scst_init_cmd_list to avoid that
commands get stuck in the command init list. This patch fixes the
following race condition that can occur if SCST_FLAG_SUSPENDED
has been set and if scst_init_cmd_list is not empty:
* scst_do_job_init() returns to scst_init_thread() and leaves the
commands that were on the init list on that list.
* scst_init_thread() invokes test_init_cmd_list().
* test_init_cmd_list() returns false because SCST_FLAG_SUSPENDED
has been set.
* scst_resume_activity() clears SCST_FLAG_SUSPENDED and invokes
wake_up_all(&scst_init_cmd_list_waitQ). However, since
scst_init_thread() has not yet added the init thread back to
scst_init_cmd_list_waitQ this wake_up_all() call doesn't do
anything.
* scst_init_thread() adds the init thread to scst_init_cmd_list_waitQ
and unlocks scst_init_lock.
Additionally, remove an unneeded smp_mb__after_clear_bit() call.
wake_up_all() guarantees that if it wakes up a thread that that
thread sees all store operations that were performed by the thread
that invoked wake_up_all() and that preceeded the wake_up_all()
invocation.

scst: Avoid that smatch complains about dead code
The panic() function that implements BUG() has been declared with attribute
noreturn in some RHEL 5 kernel headers and also in the RHEL 6 kernel headers.
Smatch warns about dead code if any code follows a function that has been
declared with attribute noreturn. Hence add a few preprocessor statements to
suppress the smatch warning when building against an upstream kernel or when
building against RHEL 6 or later.

isert: Fix race between target_del_all() and iscsit_unregister_transport()
When iscsi-scstd exits for some reason, release on character device ctr_name is called. The release function of this character device calls target_del_all(). In order to avoid a scenario where isert-scst is being removed at the same time as iscsi-scstd is closing ctr_name device, increment reference count in portal creation so that the module will not disappear before target_del_all() finishes using it. This scenario is only relevant for isert-scst, as iscsi-scst will have positive reference count at least untill target_del_all() finishes due to __fput() being called only after the release method of the character device has returned.

Hush Coverity warning of scst_ws_push_single_write() uninitialized pointer
Coverity warns that sgv may be used uninitialized. The warning
applies to WRITE SAME commands with LBDATA == PBDATA == 0 (replicate
a single block of user data into the specified LBA range).
The warning appears to be spurious - when LBDATA == PBDATA == 0,
scst_ws_write_cmd_finished() will not use the uninitialized value
saved by scst_ws_push_single_write().
Move initialization of sgv earlier in the function to quiesce the warning.

scst_user, rt: Wake command processing thread when needed
In a fully-preemptible realtime kernel (CONFIG_PREEMPT_RT_FULL=y),
SCSI commands from an initiator time out because the userland target
application is never woken to process them.
This is because in a fully-preemptible realtime kernel, soft-IRQ
(tasklet) execution always occurs in a ksoftirqd thread and
preempt_count is not manipulated on soft-IRQ processing entry/exit.
This makes in_interrupt() useless for determining whether soft-IRQ
processing is occurring; instead, in_serving_softirq() should be
used for that purpose.

Fix spurious BUG when parse_type != SCST_USER_PARSE_STANDARD
Changeset 4224 introduced EXTRACHECKS for valid lba/data_len and state
at the end of the parsing phase of command processing.
However, the checks do not account for deferral of parsing to userland,
as occurs when SCST_USER_PARSE_CALL or SCST_USER_PARSE_EXCEPTION are specified.
In such cases the checks report errors on commands that userland has not yet
had an opportunity to parse.
NOTE: this includes a refactoring of the EXTRACHECKS to improve clarity.
The rework is not exactly equivalent to the original code, but does
conform to the comments describing the original code.
Specifically, the original code would not trap an illegal command state
unless there was also an illegal lba or data_len.

Makefiles: calculate KVER properly
When deriving the kernel version (KVER) from KDIR, the file
$(KDIR)/include/config/kernel.release should be preferred over
'make kernelversion'.
For example, the Ubuntu 3.2.0-23-generic kernel has a kernel.release
file containing '3.2.0-23-generic', but 'make kernelversion' returns
3.2.14. Since the modules are stored under /lib/modules/3.2.0-23-generic,
the value in kernel.release is the correct one to use.
Also:
- Evaluate KVER only once
- All depmod commands must include KVER

scst, qla2x00t: Prevent inappropriate sleeping with a real-time kernel
With a realtime kernel with full preemption (CONFIG_PREEMPT_RT_FULL),
spinlocks can sleep, interrupt handlers run in thread context, and
the standard local_irq functions manipulate preemptibility, not HW
interruptibility. Under these conditions, most calls to local_irq
functions should be replaced by no-ops. The CONFIG_PREEMPT_RT patch
defines _nort versions of local_irq functions that compile away
under CONFIG_PREEMPT_RT_FULL and compile to their "normal"
equivalents otherwise.
Define _nort equivalents to support compilation against both
"normal" and RT-patched kernels, and use the _nort local_irq
functons in cases where spinlocks are taken within a
local_irq_save() or local_irq_disable() block. Without these
changes, runtime warnings about "sleeping function called from
invalid context" occur.

isert: Fix case when iscsid is not able to handle login request on time or at all
In some cases, iscsi-scstd chooses to close the connection device and abort the connection. This can cause invalid device state due to order of isert_conn_dev cleanup and disconnect handling. Make sure we release isert_conn_dev only after we received disconnect event, or we passed the connection to the kernel. This also fixes an issue if iscsi-scstd is run on very CPU intensive load and it does not receive CPU time to serve the login requests.
