It was an effort to enhance fscache as a kernel cache for lazy pulling (at least according to previous Incremental FS discussion [1]) and EROFS over fscache was the in-tree user of this mode. fscache has since evolved to be netfslib-oriented, serving network filesystem inodes via the netfs library, but EROFS never acts as a network filesystem and we need to cache golden filesystem images rather than individual EROFS inodes. Since EROFS over fscache is now removed, clean up netfs/fscache/ cachefiles upstream too.

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.

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

|
|
help
|
|
This permits error injection to be enabled in cachefiles whilst a
|
|
cache is in service.
