I'm unhappy about it (obviously), but it's an uphill battle. Sometimes the poster would actually *like* to bottom post, but the tooling (which may not be their own choice) gets in their way. I suggest always scrolling to the bottom, or at least until you see a signature. Thanks, Laszlo ___ edk2-devel mailing list edk2-devel@lists.01.org https://lists.01.org/mailman/listinfo/edk2-devel

The 'git backport-diff' tool is very powerful to resume differencies between 2 series, in particular when the project evolved between versions of a series (simplest example: a rebase): https://github.com/codyprime/git-scripts/blob/master/git-backport-diff#L27 Sadly I can't find a distribution handy package that provides it, so it has to be installed manually.

Thanks Ard and Laszlo. For the minor change in single patch, the patch may be sent separately with the clear subject. Or, the patch set can be sent again.

I think resending one patch can be acceptable, but the subject line
(patch nr) and the threading have to be correct. Also, I don't think
this approach scales beyond exactly one patch-update; it's easy to lose
track of version numbers etc. So "use sparingly" I guess? :)

Hi, Jiaxin
Yes the full patch series is needed for a v2 version.
And also, why you removed the "(Instance->Token != NULL)" check in the if
condition?

Laszlo may disagree with me, but I think that it is not always
necessary to resend the entire series when only a single patch
changes. It does depend on the situation, though: if it is a trivial
patch in a more complicated series then it might make little sense. In
other case, just resending the whole thing is probably better.

This is my idea to avoid the duplicated mail. I also include Ard and Laszlo to
collect the feedback on how to handle the partial update in the patchset.

Re: [edk2] [PATCH v2 1/3] MdeModulePkg/Dhcp4Dxe: Remove unnecessary NULL pointer check.
