In core function, the instances of some client resource structures are maintained by IDR. As of kernel v6.0, IDR has been superseded by XArray and deprecated. This commit replaces the usage of IDR with XArray to maintain the resource instances. The instance of XArray is allocated per client with XA_FLAGS_ALLOC1 so that the index of allocated entry is greater than zero and returns to user space client as handle of the resource.

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.
