You must have screwed up your git request-pull somehow.

Yes, yes, the above works, and a branch is just a named SHA1. You can
give the SHA1 directly.

But it's not what you meant to do, I'm sure. Especially since you
pointed to the SHA1 of the top commit, not the tag that you have that
points to it.

I can see what you _meant_ to ask me to pull with "git ls-remote". I
clearly should - and will - pull the 'pci-v5.6-changes' tag, which
points to that commit.

But can you check what in your workflow went wrong for the above to happen?

Oooh, I'm sorry, that's my fault; I did screw it up.  I usually do
this:

  git request-pull origin/master git://git.kernel.org/pub/scm/linux/kernel/git/helgaas/pci.git $COMMIT > msg.txt
  git tag -s $TAG $COMMIT
  git push pci $TAG
  git request-pull origin/master git://git.kernel.org/pub/scm/linux/kernel/git/helgaas/pci.git $TAG > msg.txt

so I can look over the updates one last time before tagging, but I got
distracted in the middle and I think I forgot to do the second
request-pull after pushing the tag.

Thanks for compensating.

Bjorn
