| 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. |
