You don't get it.

Your commit message uses the  phrase  "the  following  [patch]",  but
nobody knows what this "following one" is. I do not know it even now,
while  we  are  discussing it. Please use some form of reference that
can be understood.

I do understand the situation and what you are trying to do.

What I do not understand is the sentence you wrote in the commit
message.

Ah.
