How to write a proper commit message:
1. Prepare the context for the explanation briefly.
2. Explain the problem at hand.
3. "It happens because of <...>"
4. "Fix it by doing X"
5. "(Potentially do Y)."
For more detailed info, see Documentation/process/submitting-patches.rst, Section "2) Describe your changes".
Thx.
