      [PATCH] USB: Make hub driver use usb_kill_urb() · 5106784c
      Alan Stern authored
      This is a rerun of as278, updated to match the current source.  It changes
      the hub driver, replacing calls to synchronous usb_unlink_urb() with
      usb_kill_urb() and removing the machinery formerly needed to synchronize
      the status URB handler with the rest of the driver.

      [PATCH] USB: Add usb_kill_urb() · 1d92d8c6
      Alan Stern authored
      This patch is a slightly revised version of as277c, updated to match the
      current source.  The only difference from the older version is that this
      makes urb->use_count into an atomic_t, to avoid the overhead of an extra
      locking step each time an URB is submitted and given back.  The important
      features of this patch are:
      
      	-EPERM added to Documentation/usb/error-codes.txt.
      
      	Failure to use URB_ASYNC_UNLINK with usb_unlink_urb() is
      	deprecated in the documentation.
      
      	New ->reject and ->use_count fields added to struct urb.
      	The reject field is protected by urb->lock, and locking is
      	required only in usb_kill_urb() which doesn't have to be fast.
      
      	Single wait_queue used for all processes waiting inside
      	usb_kill_urb().  The wait queue is woken up only when an URB
      	is given back with ->reject set.
      
      	usb_rh_status_dequeue() changed to return int.  It looks like
      	this function should be declared static; it's not used outside
      	the hcd.c file.
      
      	Prototype for unlink_urb() in struct usb_operations is changed
      	to include a status code argument.  This is necessary so that
      	the different unlink paths can return -ENOENT and -ECONNRESET
      	as appropriate.
      
      	Support for synchronous usb_unlink_urb() has been removed;
      	such calls are passed to usb_kill_urb().
      
      	Kerneldoc for usb_unlink_urb() is updated.
      
      	usb_kill_urb() added to urb.c.
      
      	hc_simple() host driver is partially updated -- it should
      	compile but it won't really work right.
