Hi!

This is an automated message. This series looks like a fix, but its
commit messages seem to be missing some information:

 - How the issue was discovered, e.g. hit in production, hit during
   development, syzbot report, manual code inspection, LLM or static
   analysis tool scan.

 - Whether the issue was actually triggered, or is only theoretical
   (e.g. found by code inspection). If it was triggered please include
   the symptoms, like the stack trace or error messages.

 - What hardware the change was tested on. For driver fixes please
   mention the device (and if relevant firmware version) used for
   testing, or say that the change was not tested on real hardware.

Please do not repost the series just to address the above. Instead,
reply to this email with the missing information, so that reviewers
can take it into account. If the series needs another revision for
other reasons, please include the information in the commit messages
then.

The evaluation is done by an LLM so it may be wrong, if you think
that is the case please reply and explain.

I was reminded what I complicated mess skb frag accounting currently
is when I looked at this patch:

[1] https://lore.kernel.org/netdev/xfrm-iptfs-pp_ref_count-underflow-v4-1-912fa72106f0@secunet.com/ (local)


And saw that the author was trying to write their own skb frag helper
inside the driver because core didn't provide one that made sense :/
code inspection + LLM written tests for accounting confirmed the
issues. I worked with the LLM to fix the discovered issues. Not hit in
production or reproduced organically. Only code inspection and
artificial tests.
