----------------------------------------------------------------
Driver core changes for 6.16-rc1

Here are the driver core / kernfs changes for 6.16-rc1.

Not a huge number of changes this development cycle, here's the summary
of what is included in here:
  - kernfs locking tweaks, pushing some global locks down into a per-fs
    image lock
  - rust driver core and pci device bindings added for new features.
  - sysfs const work for bin_attributes.  This churn should now be
    completed for those types of attributes
  - auxbus device creation helpers added
  - fauxbus fix for creating sysfs files after the probe completed
    properly
  - other tiny updates for driver core things.

All of these have been in linux-next for over a week with no reported
issues.

This is missing the switch away and removal of the transitional
struct members, "read_new", "write_new" and "bin_attrs_new".
These are the actually churny changes.

I have a branch with those, based on current linux-next/master, at
https://git.kernel.org/pub/scm/linux/kernel/git/thomas.weissschuh/linux.git b4/sysfs-const-bin_attr-final

(Has not yet passed 0day, but earlier versions this week did)

Do you want me to resubmit it to you? Now or shortly before the end of
the merge window?

Ah, yes, those are still in my "to apply after -rc1 is out" queue, sorry
about that.  And yes, I'll be glad to take updated versions as things
have changed.

In case you don't see patches submitted during the merge window,
here is the updated series:

https://lore.kernel.org/lkml/20250530-sysfs-const-bin_attr-final-v3-0-724bfcf05b99@weissschuh.net/

Based on linux-next to make sure that all changes that could go into the
merge window are accounted for.
