I have *absolutely* no clue what this commit message is trying to tell me - sorry you'd have to try again. Maybe structuring it this way, would help: -- Problem is A. It happens because of B. Fix it by doing C. (Potentially do D). For more detailed info, see Documentation/process/submitting-patches.rst, Section "2) Describe your changes". Also, to the tone, from Documentation/process/submitting-patches.rst: "Describe your changes in imperative mood, e.g. "make xyzzy do frotz" instead of "[This patch] makes xyzzy do frotz" or "[I] changed xyzzy to do frotz", as if you are giving orders to the codebase to change its behaviour." Also, do not talk about what your patch does - that should hopefully be visible in the diff itself. Rather, talk about *why* you're doing what you're doing. -- Regards/Gruss, Boris. https://people.kernel.org/tglx/notes-about-netiquette
