config NETFS_SUPPORT
tristate
help
This option enables support for network filesystems, including
helpers for high-level buffered I/O, abstracting out read
segmentation, local caching and transparent huge page support.
config NETFS_STATS
bool "Gather statistical information on local caching"
depends on NETFS_SUPPORT && PROC_FS
help
This option causes statistical information to be gathered on local
caching and exported through file:
/proc/fs/fscache/stats
The gathering of statistics adds a certain amount of overhead to
execution as there are a quite a few stats gathered, and on a
multi-CPU system these may be on cachelines that keep bouncing
between CPUs. On the other hand, the stats are very useful for
debugging purposes. Saying 'Y' here is recommended.
config NETFS_DEBUG
bool "Enable dynamic debugging netfslib and FS-Cache"
depends on NETFS_SUPPORT
help
This permits debugging to be dynamically enabled in the local caching
management module. If this is set, the debugging output may be
enabled by setting bits in /sys/module/netfs/parameters/debug.
config FSCACHE
bool "General filesystem local caching manager"
depends on NETFS_SUPPORT
help
This option enables a generic filesystem caching manager that can be
used by various network and other filesystems to cache data locally.
Different sorts of caches can be plugged in, depending on the
resources available.
See Documentation/filesystems/caching/fscache.rst for more information.
config FSCACHE_STATS
bool "Gather statistical information on local caching"
depends on FSCACHE && PROC_FS
select NETFS_STATS

caching and exported through file:
