Fixed this and the other one. Pavel, JFYI. What I usually say is
add:

[pretty]
	fixes = Fixes: %h (\"%s\")

[alias]
	fixes = log -1 --format=fixes

to your ~/.gitconfig so you can just run:

$ git fixes 8c0cab0b7bf768594e8efc73f7b8f3d5abeb74f1
Fixes: 8c0cab0b7bf7 ("io_uring/zcrx: always dma map in advance")

and it does the right thing for you. Nobody remembers that full git log
line, and then people try and do it manually, and invariably mess up the
formatting. git fixes <sha> is the way.
