| 7 | This option enables a generic filesystem caching manager that can be | |
| 8 | used by various network and other filesystems to cache data locally. | |
| 9 | Different sorts of caches can be plugged in, depending on the | |
| 10 | resources available. | |

| 19 | This option causes statistical information to be gathered on local | |
| 20 | caching and exported through file: | |
| 21 | ||
| 22 | /proc/fs/fscache/stats | |
| 23 | ||
| 24 | The gathering of statistics adds a certain amount of overhead to | |
| 25 | execution as there are a quite a few stats gathered, and on a | |
| 26 | multi-CPU system these may be on cachelines that keep bouncing | |
| 27 | between CPUs. On the other hand, the stats are very useful for | |
| 28 | debugging purposes. Saying 'Y' here is recommended. | |

| 36 | This permits debugging to be dynamically enabled in the local caching | |
| 37 | management module. If this is set, the debugging output may be | |
| 38 | enabled by setting bits in /sys/modules/fscache/parameter/debug. | |
