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.

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.

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.
