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:

            ^^^^

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

Hi Kuan, it was genuinely my mistake. I forgot to run check patch before sending it over. And this happened. I'll give it a bit before sending over a V2 fixing these issues :)

Additionally, I believe many different people have already pointed out
the word-wrapping issues in your replies. Some developers are even
getting frustrated because of the repeated reminders. You have promised
to fix this, yet every time you send a new email, the exact same
problem persists.

I would suggest that you figure out how to completely resolve this
issue before attempting to submit new patches. Furthermore, you
recently mentioned that you were going to take a break for a while, but
less than a few days later, I am already receiving another patch from
you.
