3b23f6d223 Merge of the trunk's r3151 and 3152: 
Cleanup: eliminate a superfluous cast and unnest an if-statement

and

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.

e6fb3b2a1d scst/scst_vdisk: Made error handling in bi_end_io function IRQ-safe since 
bi_end_io functions must be IRQ-safe.

A quote from a discussion between Alan Cox, Mikulas Patocka and Jens Axboe
(http://lkml.org/lkml/2008/7/2/69):

> >Right, that wont work of course. Completions are typically done through
> >a softirq, so it is not currently done with hard interrupts disabled.
>
> I thought, from hardirq - that's what IDE is doing. And they are called

The key word is 'typically', the old IDE driver really isn't used very
much. The SCSI layer and eg cciss uses the block layer softirq
completions, so that is what 99% of the uses will be.

The patch itself was provided by Arne Redlich.

ddc2387ec5 Merge of the trunk's r2860: 
This patch fixes a class of race conditions in the ..._sysfs_del()
functions: the kobject_put() calls should come after all kobject_del() calls
because as long as the last kobject_del() call hasn't been invoked, a sysfs
.show() or .store() callback may still be in progress that needs one of
these kobjects.
