In linux kernel since version 3.17 (release Date: 2014-10-05)  
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.
