- 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.
