We currently use it for find_or_create_page(), which means that it cannot fail. Ensure we also pass in 'retry == true' to alloc_page_buffers(), which also ensure that it cannot fail. After this, there are no failure cases in grow_dev_page() that occur because of a failed memory allocation.

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.
