You may like to limit the git log brief description to 50 characters
(this is going to be hard with such a long pre-fix though :)
Brief description should be in imperative mood i.e 'Fix foo' instead of
'fixed foo'.

This is not descriptive enough. You may like to read
Documentation/process/submitting-patches.rst
for tips on writing git log messages.

The code was easier to read before this change IMO.

Likewise, this is not making the code easier to read.

Remember, we are writing code for developers to read. It should be as
easy to parse as possible.
Hope this helps,
Tobin.
