The default case for dax_dev_huge_fault() fault size handling mistakenly returns when it should unlock. This is not a problem in practice since the only three possible fault sizes are handled. Going forward, if the core mm adds a new fault size beyond pte, pmd, or pud device-dax should abort VM_FAULT_SIGBUS requests not VM_FAULT_FALLBACK since device-dax guarantees a configured fault granularity for all faults.

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.
