Worth nothing here that linux-headers patches should be generated using
scripts/update-linux-headers.sh.
Since this linux-headers update includes changes that aren't merged into the
kernel yet, I would still use update-linux-headers.sh -- but also include in
the commit message that this is a placeholder patch that includes unmerged uapi
changes. Then once the kernel changes merge you can just have a proper
linux-headers update patch in a subsequent qemu series.
I guess I do not understand the procedure here. I first determined the
latest kernel release in which the vfio.h file was updated with the
following command:
git log --oneline origin/master -- linux-headers/linux/vfio.h
According to the git log, the vfio.h file was last updated in kernel
v6.3-rc5. I cloned that kernel from
git.kernel.org/pub/scm/linux/kernel/git/stable and checked out kernel
6.3-rc5. I then made the changes to the linux-headers/linux/vfio.h file
and ran the update-linux-headers.sh script and created this patch from
that. Where did I go wrong?
