Driver core / kernfs changes for 6.0-rc1
Here is the set of driver core and kernfs changes for 6.0-rc1.
"biggest" thing in here is some scalability improvements for kernfs for
large systems. Other than that, included in here are:
- arch topology and cache info changes that have been reviewed
and discussed a lot.
- potential error path cleanup fixes
- deferred driver probe cleanups
- firmware loader cleanups and tweaks
- documentation updates
- other small things
All of these have been in the linux-next tree for a while with no
reported problems.
