  59 /* Locking and synchronization:
  60  *
  61  * The basic principle is that everything is serialized through a
  62  * single spinlock, priv->lock.  The lock is used in user, bh and irq
  63  * context, so when taken outside hardirq context it should always be
  64  * taken with interrupts disabled.  The lock protects both the
  65  * hardware and the struct orinoco_private.
  66  *
  67  * Another flag, priv->hw_unavailable indicates that the hardware is
  68  * unavailable for an extended period of time (e.g. suspended, or in
  69  * the middle of a hard reset).  This flag is protected by the
  70  * spinlock.  All code which touches the hardware should check the
  71  * flag after taking the lock, and if it is set, give up on whatever
  72  * they are doing and drop the lock again.  The orinoco_lock()
  73  * function handles this (it unlocks and returns -EBUSY if
  74  * hw_unavailable is non-zero).
