+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.rst 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_ERROR_INJECTION
+ bool "Provide error injection for cachefiles"
+ depends on CACHEFILES && SYSCTL
+ help
+ This permits error injection to be enabled in cachefiles whilst a
+ cache is in service.
+
+config CACHEFILES_ONDEMAND
+ bool "Support for on-demand read"
+ depends on CACHEFILES
+ default n
+ help
+ This permits userspace to enable the cachefiles on-demand read mode.
+ In this mode, when a cache miss occurs, responsibility for fetching
+ the data lies with the cachefiles backend instead of with the netfs
+ and is delegated to userspace.
+
+ If unsure, say N.
