It's not good to crash the machine if panic_on_warn() is set just because someone made a stupid mistake of trying to create a sysfs file with the same name of an existing one. This makes the automated testing tools a lot harder to find the real bugs in the kernel. So just print a warning out and dump the stack to get the attention of the developer that they did something foolish. Then keep on trucking, as this should not be a fatal error at all.

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.
