I propose to split the adjustment of two function implementations
into separate update steps for a small patch series.
https://git.kernel.org/pub/scm/linux/kernel/git/torvalds/linux.git/tree/Documentation/process/submitting-patches.rst?id=625d3449788f85569096780592549d0340e9c0c7#n138

I suggest to improve the change descriptions accordingly.
