| * This code is deliberately kept separate from the main industrialio I/O core |
| * as it is intended that in the future a number of different software ring |
| * buffer implementations will exist with different characteristics to suit |
| * different applications. |
| * |
| * This particular one was designed for a data capture application where it was |
| * particularly important that no userspace reads would interrupt the capture |
| * process. To this end the ring is not locked during a read. |
| * |
| * Comments on this buffer design welcomed. It's far from efficient and some of |
| * my understanding of the effects of scheduling on this are somewhat limited. |
| * Frankly, to my mind, this is the current weak point in the industrial I/O |
| * patch set. |
