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.
