    Merge tag 'configfs-7.4-rc1' of git://git.kernel.org/pub/scm/linux/kernel/git/leitao/linux

    Pull configfs updates from Breno Leitao:

     - Attribute structures can now be const (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.
