0014 This option causes statistical information to be gathered on local
0015 caching and exported through file:
0016
0017 /proc/fs/fscache/stats
0018
0019 The gathering of statistics adds a certain amount of overhead to
0020 execution as there are a quite a few stats gathered, and on a
0021 multi-CPU system these may be on cachelines that keep bouncing
0022 between CPUs. On the other hand, the stats are very useful for
0023 debugging purposes. Saying 'Y' here is recommended.
