Call directly into acpica to load a table to obtain its index on return. We choose the direct call of acpica internal functions to avoid having to modify its API which is used outside of Linux as well. Use that index to unload the table again when the corresponding directory in configfs gets removed. This allows to change SSDTs without rebooting the system. It also allows to destroy devices again that a dynamically loaded SSDT created. This is widely similar to the DT overlay behavior.

Linux kernel ============ This file was moved to Documentation/admin-guide/README.rst Please notice that there are several guides for kernel developers and users. These guides can be rendered in a number of formats, like HTML and PDF. In order to build the documentation, use ``make htmldocs`` or ``make pdfdocs``. There are various text files in the Documentation/ subdirectory, several of them using the Restructured Text markup notation. See Documentation/00-INDEX for a list of what is contained in each file. 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.
