| 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). |
