Linux kernel modifications for the Kernel Hacking exam
9cd5881719
Due to the complexity of client->remove() callbacks it is desirable to not hold any locks while calling them. Remove the last one by tracking only the highest client ID and running backwards from there over the xarray. Since the only purpose of that lock was to protect the linked list, we can drop the lock.

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.
