checkpatch.pl generates the following warnings:

WARNING: Prefer a maximum 75 chars per line (possible unwrapped commit description?)
#60:
Since there isnt much tests for lib/glob.c, lets go ahead and add some more tests

WARNING: 'isnt' may be misspelled - perhaps 'isn't'?
#60:
Since there isnt much tests for lib/glob.c, lets go ahead and add some more tests
^^^^

total: 0 errors, 2 warnings, 31 lines checked

I have mentioned this to you multiple times in the past: please always
run checkpatch.pl to check your patches before sending them.

Regards,
Kuan-Wei
