- Change socket lock users to owner which is a pointer.
- Add sock_owned_by_user

- The media is allowed not to have any support for
link-level multicasts, ppp is an example.

This fixes some critical bugs in cpqarray in 2.5.  One of the fixes
essentially backs out the block queue stop/start behavior that was added
recently.  This code as it stands is buggy and locks up under even light
SMP workloads.  Certainly we want the performance benefits of proper
block queue plugging, but the driver needs some work before it will fit
nicely.

Some of these fixes do theoretically hurt performance, but when you
consider that the driver is unusable under SMP as-is, I think it is
right to get correctness first.

Specifically, this patch does the following:

* Adds locking to proc queue-walking code for debugging use.  Note that
  the proc registration is still broken and I've left it that way since
  this stuff should probably migrate to driverfs anyway.

* Moves interrupt enabling so queue lock is initialized before
  interrupts are enabled.  Otherwise if we get a quick interrupt we oops
  the machine.

* Removes unconditional IRQ enabling in do_ida_request().  The block
  layer takes the spinlock with irq_save so if we're going to play this
  trick then we need to irq_restore.  For now, just eliminate the
  unlocked region.

* Remove block queue stop/start logic since it can leave the queue
  stopped with no outstanding completions to start it again.  Plugging
  logic can come back but it should go hand-in-hand with a cleanup of
  the driver's request handling algorithm.  If nobody screams about this
  patch I'll go ahead and start making those improvments.

This last patch removes the union, replacing it with s_fs_info.
