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.
See Documentation/filesystems/caching/fscache.rst for more information.
