A) If you want to have proper commit logs, you will usually do two things: first create a commit title, which is what appears in the above summary. That commit title should not be longer than 72 characters, and it should explain roughly what you're trying to do. The actual description should be in the commit log itself, and you should document what is the issue you're trying to fix / improve, how you're doing it and why you've done it that way. The final line of that commit log shoud be your Signed-off-by, which is your agreement to the Developer Certificate of Origin (DCO), that you'll find documented here: https://git.kernel.org/pub/scm/linux/kernel/git/torvalds/linux.git/tree/Documentation/process/submitting-patches.rst#n429 B) Please base your work on a known release (4.14) and not the middle of Linus' branch. C) I'm not sure what you tried to do with the application of the request API patches (such as e1ca861c168f) but we want to have the whole commits in there, and not a patch adding all of them. This will make the work so much easier to rebase to a later version when some patches wouldn't have been merged and some would have. D) Rebase :) Thanks!
