Vladislav Bolkhovitin 25dd5b2e2e I/O context creation and cleanup in SCST command-processing threads is 
protected by io_context_mutex. The patch below changes that mutex from a
single mutex for all command threads to one mutex per thread pool.

+

Two quickly succeeding command thread management actions, e.g. setting both
threads_num and threads_pool_type via scst.conf, can trigger the bug mentioned
below. That bug can be triggered because kthread_stop() can stop a thread
before it has started. So it can happen that an I/O context is created inside
scst_cmd_thread() but not cleaned up because the thread for which
p_cmd_threads->nr_threads == 1would evaluate to true is never started. The
patch below fixes this by guaranteeing that if an I/O context has been created
for a thread pool that it gets cleaned up too.

Vladislav Bolkhovitin cef1b4cdff The changes included in the patch below are: 
- If someone tries to build SCST on an RHEL 5 system without having
run 'make enable_proc' first, complain.
- Do not define set_cpus_allowed_ptr() on RHEL 5 since RHEL 5 does
have a declaration for this function.
  The function itself is not exported from the kernel however (this is probably a bug). Because of that, replace
the call to set_cpus_allowed_ptr() in scst_main.c by a call to set_cpus_allowed().
- Do not define the variable 'err' on kernels where that variable is
not used in order to avoid a compiler warning.
- Also in scst_vdisk.c, pass a 16-bit value as the first argument of
put_unaligned() when writing to a 16-bit variable in order to avoid a compiler warning.

Signed-off-by: Bart Van Assche <bvanassche@acm.org>

with fixes and additions:

 - In scst_vdisk.c we need 32-bit values, not 16, fixed
 - Optimal UNMAP granuality changed to 1.
