Hi Peter,

this patch looks good to me, however a few tweaks are needed to the
submission in order for it to enter the review pipeline, and thus
path to being accepted.

1. For networking patches, please specify the target tree.
Fixes go to 'net'. Other patches go to 'net-next'
This appears to be in the latter category. So:

Subject: [PATCH net-next] ...

2. Looking at the git history of include/linux/skbuff.h,
it seems that 'net: skbuff: is the preferred prefix.
So:

Subject: [PATCH net-next] net: skubff: ...

3. Please CC netdev@xxxxxxxxxxxxxxx

This is the most important part, else our automated systems don't see
the patch, and it doesn't exist in the pipeline.

As an aside, in general, and in this case, there is no need to copy
linux-kernel@xxxxxxxxxxxxxxx on Networking patches.

4. Please do CC parties to any patches mentioned, in this case
ac45f602ee3d. Which I think means:

Patrick Ohly <patrick.ohly@xxxxxxxxx>
