When parsing a schema configuration value from user-space, resctrl walks the architectures rdt_resources_all[] array to find a matching struct rdt_resource. Once the CDP resources are merged there will be one resource in use by two schemata. Anything walking rdt_resources_all[] on behalf of a user-space request should walk the list of struct resctrl_schema instead. Change the users of for_each_alloc_enabled_rdt_resource() to walk the schema instead. Schemata were only created for alloc_enabled resources so these two lists are currently equivalent. schemata_list_create() and rdt_kill_sb() are ignored. The first creates the schema list, and will eventually loop over the resource indexes using an arch helper to retrieve the resource. rdt_kill_sb() will eventually make use of an arch 'reset everything' helper. After the filesystem code is moved, rdtgroup_pseudo_locked_in_hierarchy() remains part of the x86 specific hooks to support pseudo lock. This code walks each domain, and still does this after the separate resources are merged.

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.
