Help text

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.
