We need to move to per-cpu state for both deferred inode inactivation and CIL tracking, but to do that we need to handle CPUs being removed from the system by the hot-plug code. Introduce generic XFS infrastructure to handle CPU hotplug events that is set up at module init time and torn down at module exit time. Initially, we only need CPU dead notifications, so we only set up a callback for these notifications. The infrastructure can be updated in future for other CPU hotplug state machine notifications easily if ever needed.

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.
