Now that the fscache code is moved to be colocated with the netfslib code so that they combined into one module, do the combining.

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.
