Donenfeld <Jason@...c4.com> 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.
