- config FSCACHE
- tristate "General filesystem local caching manager"
- help
- 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.txt for more information.
- config FSCACHE_STATS
- bool "Gather statistical information on local caching"
- depends on FSCACHE && 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.
- See Documentation/filesystems/caching/fscache.txt for more information.
- config FSCACHE_HISTOGRAM
- bool "Gather latency information on local caching"
- depends on FSCACHE && PROC_FS
- help
- This option causes latency information to be gathered on local
- caching and exported through file:
- /proc/fs/fscache/histogram
- The generation of this histogram adds a certain amount of overhead to
- execution as there are a number of points at which data is gathered,
- and on a multi-CPU system these may be on cachelines that keep
- bouncing between CPUs. On the other hand, the histogram may be
- useful for debugging purposes. Saying 'N' here is recommended.
- See Documentation/filesystems/caching/fscache.txt for more information.
- config FSCACHE_DEBUG
- bool "Debug FS-Cache"
- depends on FSCACHE
- help
- 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.
- See Documentation/filesystems/caching/fscache.txt for more information.
- config FSCACHE_OBJECT_LIST
- bool "Maintain global object list for debugging purposes"
- depends on FSCACHE && PROC_FS
- help
- Maintain a global list of active fscache objects that can be
- retrieved through /proc/fs/fscache/objects for debugging purposes
