[GIT PULL] configfs: Updates for 7.4

[Breno Leitao]

Linus,

Please consider pulling these configfs updates for 7.4-rc1.

There are three parts: Thomas Weißschuh's series that allows const
configfs attribute structures, new selftests for the userspace
interface, and three Rust binding changes that I merged from Andreas
Hindborg's signed tag.

FWIW: The const series touches three drivers outside fs/configfs (acpi, xe,
coco/guest report) because they implement the callbacks and bin attributes
whose types change.

Thanks,
--breno

configfs: Updates for v7.4

- Attribute structures can now be const. From Thomas Weißschuh.

- The first selftests for the configfs userspace interface, plus a
  sample subsystem that accepts symlinks to test against. They include
  a race of symlink(2) against rmdir of the target, which exercises
  the use-after-free fixed in v7.3-rc3.

- Rust bindings, merged from Andreas Hindborg's signed tag: fix the
  data offset calculation in subsystem callbacks (marked for stable),
  add the missing Send and Sync bounds, and correct a safety comment.
