# SPDX-License-Identifier: GPL-2.0-only 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.
