[ Upstream commit 014704e6f54189a203cc14c7c0bb411b940241bc ] The "count < sizeof(struct os_area_db)" comparison is type promoted to size_t so negative values of "count" are treated as very high values and we accidentally return success instead of a negative error code. This doesn't really change runtime much but it fixes a static checker warning.

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.
