It means that other feature depends on CONFIG_DEBUG_FS.
I can suggest running script like following to detect possible decencies.

find -type f -name Kconfig | xargs grep -B3  "DEBUG_FS"

FYI
Menu items beginning with following braces represent features that
[ ] can be built in or removed
< > can be built in, modularized or removed
{ } can be built in or modularized (selected by other feature)
- - are selected by other feature,
while *, M or whitespace inside braces means to build in, build as a
module or to exclude the feature respectively.
