Bhanu Gollapudi fee787129d [SCSI] bnx2fc: IO completion not processed due to missed wakeup
Driver does not detect a new CQE (completion queue entry) if a thread receives
the wakup when it is in TASK_RUNNING state. Fix is to set the state to
TASK_INTERRUPTIBLE while holding the fp_work_lock.

Also, Use __set_current_task() since it is now set inside a spinlock with
synchronization.

Two other related optimizations:

1.  After we exit the while (!kthread_should_stop()) loop, use
__set_current_state() since synchronization is no longer needed.

2.  Remove set_current_state(TASK_RUNNING) after schedule() since it
should always be TASK_RUNNING after schedule().

James Bottomley 8c3adc796f [SCSI] ses: add subenclosure support
There have been many complaints that an enclosure with subenclosures
isn't attached to by the ses driver.   Until now, though, no-one had
been willing to provide access to one.

Subenclosures are added simply by flattening the tree (i.e. all
subenclosure devices show up under the one main device).  This may have
consequences if the naming is only unique per subenclosure, but that's a
bug for another day.  The tested array had no page 7, so no device
naming at all.  It also only had the disk devices on one of its
subenclosures (all the others had power, fans, temperature and various
sensors), so testing of this is fairly rudimentary.

Bhanu Gollapudi 0ea5c27583 [SCSI] bnx2fc: common free list for cleanup commands
Cleanup commands are issued to the firmware to cleanup any stuck ios
that are supposed to be implicitly aborted. In the worst case we can
have all scsi ios filling up the free_list and we may not be able to
allocate cleanup tasks. So the driver has to reserve free_list entries
to be able to allocate the cleanup tasks. This reserve free_list common
to all cpus is allocated as one additional entry in the per cpu
free_lists.

In bnx2fc_cmd_alloc(), there is a related fix to use get_cpu() for the
free_list_index.  This will prevent using the wrong index if the CPU
is preempted.

With kernel debugging enabled, holding cq_lock when calling
bnx2fc_free_session_resc() which calls iounmap() leads to a warning
stack trace [INFO: HARDIRQ-safe -> HARDIRQ-unsafe lock order detected].
iounmap() grabs a HARDIRQ-unsafe vmlist lock, so holding
spin_lock_bh(cq_lock) when calling iounmap() will trigger the LOCKDEP
warning.  Since cq_lock is required only to guard against deletion, hold
the lock just before freeing the cq.

Jesper Juhl 0bf8c86970 Reduce sequential pointer derefs in scsi_error.c and reduce size as well
This patch reduces the number of sequential pointer derefs in
drivers/scsi/scsi_error.c

This has been submitted a number of times over a couple of years.  I
believe this version adresses all comments it has gathered over time.
Please apply or reject with a reason.

The benefits are:

 - makes the code easier to read.  Lots of sequential derefs of the same
   pointers is not easy on the eye.

 - theoretically at least, just dereferencing the pointers once can
   allow the compiler to generally slightly faster code, so in theory
   this could also be a micro speed optimization.

 - reduces size of object file (tiny effect: on x86-64, in at least one
   configuration, the text size decreased from 9439 bytes to 9400)

 - removes some pointless (mostly trailing) whitespace.
