First, your commit title and commit message have several problems:
1. Title should be: net/virtio: TITLE_OF_YOUR_COMMIT. As your patch is a
fix patch, your title maybe 'fix XXXX'.
2. Title and description too long, should be less or equal than around 75 chars
per line
3. Seems the link you attached is the bad commit you want to fix. Please use
this way to point it out: add 'Fixes: BAD_COMMIT_ID ("BAD_COMMIT_TITLE")' under
the commit msg.
For all above problems, please see previous git log for reference.
And for the patch content, what is the exact issue you met? I've been told that
the deleted lines were for some CI errors. Besides, better keep the '\' aligned.
Also, please cc to related maintainers in your v2 because otherwise it'll be
hard
for them to see your patch.(use get-maintainer.sh to know them)
Thanks!
