config CACHEFILES
tristate "Filesystem caching on files"
depends on FSCACHE && BLOCK
help
This permits use of a mounted filesystem as a cache for other
filesystems - primarily networking filesystems - thus allowing fast
local disk to enhance the speed of slower devices.
See Documentation/filesystems/caching/cachefiles.txt for more
information.
config CACHEFILES_DEBUG
bool "Debug CacheFiles"
depends on CACHEFILES
help
This permits debugging to be dynamically enabled in the filesystem
caching on files module. If this is set, the debugging output may be
enabled by setting bits in /sys/modules/cachefiles/parameter/debug or
by including a debugging specifier in /etc/cachefilesd.conf.
config CACHEFILES_HISTOGRAM
bool "Gather latency information on CacheFiles"
depends on CACHEFILES && PROC_FS
help
This option causes latency information to be gathered on CacheFiles
operation and exported through file:
/proc/fs/cachefiles/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/cachefiles.txt for more
information.
