If you want to give credit as you mentioned, you can add the acked-by or signed-off for Julia. But, usually, the patch description don't include the engineer's name directly.

Signed-off-by is like signing a legal document to say that you haven't stolen any of the code from SCO Unix.

You're right. I'm forcing to put the Sign-off. It is just example. But, I still think that patch description including the engineer's name is not appropriate to give the credit someone.

How about you use the Suggested-by tag as following?

The text in [ ] looks ugly. A suggested by by itself would not be appropriate, since I didn't identify the original issue. There are ther patches that refer to peoples' comments in a similar way.

I understand that but I don't understand why, though. Anyway, aren't forwarding this to someone?

Because if the name without any unique email address is included in the description, I think that it is not appropriate. Always, the information should include the email address. So, I just prefer to use the Suggested-by or the different kind of tag with [id: explanation]. But, I'll stop about it because it is not critical issue. It depend on what is the preferred method to add the information.

The only duplicates that I know about currently are Dan Williams and Xi Wang. I do sometimes get those people mixed up. I hope someday there will be another Julia Lawall duplicate as well. :) regards, dan carpenter -- To unsubscribe from this list: send the line "unsubscribe linux-pm" in the body of a message to majordomo@vger.kernel.org More majordomo info at http://vger.kernel.org/majordomo-info.html
