Commit 6b8e61472529 ("netfs: Rename CONFIG_FSCACHE_DEBUG to
CONFIG_NETFS_DEBUG") renames the config, but introduces two issues: First,
NETFS_DEBUG mistakenly depends on the non-existing config NETFS, whereas
the actual intended config is called NETFS_SUPPORT. Second, the config
renaming misses to adjust the documentation of the functionality of this
config.
Clean up those two points.

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.
