Documentation/process/submitting-patches.rst:
If your patch fixes a bug in a specific commit, e.g. you found an
issue using ``git bisect``, please use the 'Fixes:' tag with the
first 12 characters of the SHA-1 ID, and the one line summary. Do
not split the tag across multiple lines, tags are exempt from the
"wrap at 75 columns" rule in order to simplify parsing scripts.
Otherwise:
