When Rust Binder assigns a new ID, it performs various fallible operations before it "commits" to actually using the new ID. To support this pattern, change acquire_next_id() so that it does not immediately call set_bit(), but instead returns an object that may be used to call set_bit() later. The UnusedId type holds a exclusive reference to the IdPool, so it's guaranteed that nobody else can call find_unused_id() while the UnusedId object is live.

Linux kernel
============
There are several guides for kernel developers and users. These guides can
be rendered in a number of formats, like HTML and PDF. Please read
Documentation/admin-guide/README.rst first.
In order to build the documentation, use ``make htmldocs`` or
``make pdfdocs``. The formatted documentation can also be read online at:
https://www.kernel.org/doc/html/latest/
There are various text files in the Documentation/ subdirectory,
several of them using the reStructuredText markup notation.
Please read the Documentation/process/changes.rst file, as it contains the
requirements for building and running the kernel, and information about
the problems which may result by upgrading your kernel.
