2023-03-24driver core: class: use lock_class_key already present in struct subsys_privateGreg Kroah-Hartman
In commit 37e98d9bedb5 ("driver core: bus: move lock_class_key into dynamic structure"), we moved the lock_class_key into the internal structure shared by busses and classes, but only used it for buses. Move the class code to use this structure as it is already present and being allocated, instead of the statically allocated on-the-stack variable that class_create() was using as part of a macro wrapper around the core function call.

Direct access to the struct bus_type dev_root pointer is going away soon so replace that with a call to bus_get_dev_root() instead, which is what it is there for.

2023-03-17sched/debug: Put sched/domains files under the verbose flagPhil Auld
The debug files under sched/domains can take a long time to regenerate, especially when updates are done one at a time. Move these files under the sched verbose debug flag. Allow changes to verbose to trigger generation of the files. This lets a user batch the updates but still have the information available. The detailed topology printk messages are also under verbose. Discussion that lead to this approach can be found in the link below. Simplified code to maintain use of debugfs bool routines suggested by Michael Ellerman <mpe@ellerman.id.au>.

The functions device_create() and device_create_with_groups() do not modify the struct class passed into it, so enforce this by changing the function parameters to be struct const class.
