When I was doing a grep . -r /sys/kernel/debug/dri/0 I noticed a WARN appearing when I aborted the grep with ^C. After investigating I've also noticed that the error handling was lacking and there are race conditions involving multiple calls to open/close simultaneously. Fix this by setting the opened flag first and using crc->entries to decide when crc can be collected. Also call unset crc source before cleaning up, this way there is no race with a future open(). This patch has been tested with all the tests in igt with CRC in their name.

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.
