Thanks Jason. I'm trying to follow what's going on here, but I can't
find the commit hash quoted above in any of the public repositories I'm
tracking:
https://git.kernel.org/pub/scm/linux/kernel/git/torvalds/linux.git
https://git.kernel.org/pub/scm/linux/kernel/git/next/linux-next.git
https://git.kernel.org/pub/scm/linux/kernel/git/rdma/rdma.git
ssh://git.freedesktop.org/git/drm/drm
ssh://people.freedesktop.org/~agd5f/linux
ssh://people.freedesktop.org/~glisse/linux
Where is this work happening?
Thanks,
Felix
