Bring the ext4 filesystem in line with xfs that only warns and continues when the "-o dax" option is specified to mount and the backing device does not support dax. This is in preparation for removing dax support from devices that do not enable get_user_pages() operations on dax mappings. In other words 'gup' support is required and configurations that were using so called 'page-less' dax will be converted back to using the page cache. Removing the broken 'page-less' dax support is a pre-requisite for removing the "EXPERIMENTAL" warning when mounting a filesystem in dax mode.

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.
