There's really not a reason afaics that we can't just clean up everything at the end, in the terminal postclose hook: Since this is closing a file descriptor we know no one else can have a reference or a thread doing something with that drm_file except the close code. Ordering shouldn't matter, as long as we don't kfree before we clean stuff up. In the past this was more relevant when drivers still had to track and clean up pending drm events, but that's all done by the core now.

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.
