scst_vdisk: Remove a superfluous cast
The 'iov_base' member of 'struct iovec' is declared in
<uapi/linux/uio.h> with type 'void __user *'. Adding an integer
to a void pointer has the same effect as adding an integer to
a char pointer in the C language. This means that it is safe to
remove the cast in front of the eiv->iov_base pointer.
Please note that a similar construct already exists in the iSCSI
target driver. From the nthread.c source file:
iop->iov_base += rest;
iop->iov_len -= rest;
This patch does not change any functionality.

scst_vdisk: Reduce number of casts
Since 'address' points at kernel space memory, change its type
from uint8_t __user * into uint8_t *. This change reduces the
number of casts between uint8_t __user * to uint8_t * in
fileio_exec_write().

scst, iscsi-scst: Add thread_pid attribute
For SCST devices with a short name determining which SCST command
threads serve a given LUN requires an (expensive) walk of the
process table. For SCST devices with a long name it is not possible
to determine unambiguously which command threads serve a given
LUN. Hence add a thread_pid sysfs attribute that makes it easy to
figure out which command threads serve a LUN.

scst_mem: Fix a memory leak triggered by the scst_user driver
Avoid that the following memory leak can occur:
- sgv_pool_alloc() is called with SGV_POOL_RETURN_OBJ_ON_ALLOC_FAIL
set, with neither SGV_POOL_NO_ALLOC_ON_CACHE_MISS nor
SGV_POOL_ALLOC_NO_CACHED set and with 'size' such that
sgv_max_local_pages < pages_to_alloc <= pool->max_cached_pages.
- sgv_get_obj() and sgv_alloc_arrays() succeed.
- sgv_alloc_sg_entries() fails.
- sgv_get_obj() returns the SGV object with no buffers.
- A call to sgv_pool_free() adds this object to the recycle list.
- sgv_pool_alloc() is called a second time with the same parameters.
- sgv_get_obj() retrieves the object that was previously added to
the recycle list.
- sgv_alloc_arrays() is called and overwrites the obj->sg_entries
pointer although it still points at allocated memory, resulting
in a memory leak.

Stacked block devices impose weird restrictions on S/G-lists. Hence

Additionally, reduce the MAXIMUM COMPARE AND WRITE LENGTH limit from
0xff (no limit) to 0xfe to reduce the maximum amount of memory allocated
during a COMPARE AND WRITE. Also serialize COMPARE AND WRITE

ib_srpt: Make the completion vector configurable
Allow a set of completion vectors to be associated with each InfiniBand
HCA port and allocate the completion vector for each session in a
round-robin fashion from the per-port set. This helps to spread the
InfiniBand interrupt workload over multiple CPU's, at least if different
InfiniBand MSI-X vectors are associated with different CPU's.

scst: Switch from the cpu_*() to the cpumask_*() API
The cpus_*() functions were deprecated via patch "cpumask:
introduce new API, without changing anything" (November 2008,
commit ID 2d3854a37e8b). Hence switch from the cpus_*() API to
the cpumask_*() API.
This patch has the intended side effect of not adding the "[key]"
property to cpumask sysfs attributes that contain the default
cpumask. The current code namely reads uninitialized bits on
systems where nr_cpu_ids < NR_CPUS because cpus_equal() compares
more bits than those that were set by cpumask_copy().

scst_vdisk: Three more put_unaligned_*() conversions
Convert three more *(__be16 *)p = cpu_to_be16(v) statements into

convert one "cmd->dev" into "dev" expression. This patch does not
change any functionality.

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.
