+# This actually supports modular compilation, but the module overhead

+ help
+ This option provides a glob_match function for performing
+ simple text pattern matching. It originated in the ATA code
+ to blacklist particular drive models, but other device drivers
+ may need similar functionality.
+
+ All drivers in the Linux kernel tree that require this function
+ should automatically select this option. Say N unless you
+ are compiling an out-of tree driver which tells you that it
+ depends on this.

+ help
+ This option enables a simple self-test of the glob_match
+ function on startup. It is primarily useful for people
+ working on the code to ensure they haven't introduced any
+ regressions.
+
+ It only adds a little bit of code and slows kernel boot (or
+ module load) by a small amount, so you're welcome to play with
+ it, but you probably don't need it.
