The inode inactivation and CIL tracking percpu structures are per-xfs_mount structures. That means when we get a CPU dead notification, we need to then iterate all the per-cpu structure instances to process them. Rather than keeping linked lists of per-cpu structures in each subsystem, add a list of all xfs_mounts that the generic xfs_cpu_dead() function will iterate and call into each subsystem appropriately. This allows us to handle both per-mount and global XFS percpu state from xfs_cpu_dead(), and avoids the need to link subsystem structures that can be easily found from the xfs_mount into their own global lists.

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.
