| 408 | This option provides a glob_match function for performing |
| 409 | simple text pattern matching. It originated in the ATA code |
| 410 | to blacklist particular drive models, but other device drivers |
| 411 | may need similar functionality. |
| 412 | |

| 428 | It only adds a little bit of code and slows kernel boot (or |

| 430 | it, but you probably don't need it. |
