When we get an error return code from userspace (the client-core) we check to make sure it is a valid code. This patch maps the whacky return code to -EINVAL instead of propagating garbage back up the call chain potentially resulting in a hard-to-find train-wreck. The client-core doesn't have any business returning whacky return codes, but if it does, we don't want the kernel to crash as a result. Signed-off-by: Mike Marshall <hubcap@omnibond.com>
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.
