[PATCH 0/8] rust: DebugFS Bindings

[Matthew Maurer <mmaurer@google.com>]

This series provides safe DebugFS bindings for Rust, with a sample
driver using them.

The primary intended way to use these bindings is to attach a data
object to a DebugFS directory handle, and use the contents of that
attached object to serve what's inside the directory. Through a
combination of pinning and equivariance, we can ensure that the pointers
in the attached object will remain valid until after the DebugFS
directory is made inaccessible.
