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

See Documentation/filesystems/caching/fscache.rst for more information.

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.

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