| config CACHEFILES |
| tristate "Filesystem caching on files" |
| depends on NETFS_SUPPORT && 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. |
