| 56 | + ---help--- |
| 57 | + This option allows you to specify the maximum number of scatter- |
| 58 | + gather entries per I/O. The driver default is 128, which matches |
| 59 | + MAX_PHYS_SEGMENTS in most kernels. However in SuSE kernels this |
| 60 | + can be 256. However, it may decreased down to 16. Decreasing this |
| 61 | + parameter will reduce memory requirements on a per controller instance. |

| 67 | + This turns on a logging facility. |
