Please refer to commits in the form:

$(SHA1_ID) ("Commit header line.")

That is, 12 bytes of SHA1_ID followed by the commit header line text
in both double quotes and parenthesis, like this:

4d6fa57b4dab ("macsec: avoid heap overflow in skb_to_sgvec")

Otherwise when changes get backported or applied to different trees,
they have different SHA1_ID values.  The commit header text removes
any and all ambiguity.

Thank you.
