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