Considering the fact that the pattern buffer length can't be negative or 
larger that 4096, I really don't think that it is a necessary change.

Your patches should always contain only one logical change. If you, for 
instance, remove redundant blank lines, combining it with something else 
is fine, but otherwise you should split the changes up.

You don't need this text here. Usually it is the place for changelog 
between patch versions if we have more than one version of the patch. 
For instance, if you send a patch V2, it could look like this:

Signed-off-by: ...
---
V1 -> V2:
- Improve something
- Add something

So, don't repeat the commit message here :)

Anyway, great job! I believe this test could be enhanced in lots of 
ways, so I look forward to seeing new patches related to it from you :)
