Driver core changes for 6.1-rc1
Here is the big set of driver core and debug printk changes for 6.1-rc1.
Included in here is:
- dynamic debug updates for the core and the drm subsystem. The
drm changes have all been acked by the relevant maintainers.
- kernfs fixes for syzbot reported problems
- kernfs refactors and updates for cgroup requirements
- magic number cleanups and removals from the kernel tree (they
were not being used and they really did not actually do
anything.)
- other tiny cleanups
All of these have been in linux-next for a while with no reported
issues.
