While adding new partitions descriptors to the XArray the outcome of the stores should be checked and, in particular, it has also to be ensured that an existing entry with the same index was not already present, since partitions IDs are expected to be unique. Use xa_insert() instead of xa_store() since it returns -EBUSY when the index is already in use and log an error when that happens.

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 Restructured Text 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.
