We use pte_write() to check whethwer the pte entry is writable. This is mostly used to later mark the pte read only if it is writable. The other use of pte_write() is to check whether the pte_entry is writable so that hardware page table entry can be marked accordingly. This is used in kvm where we look at qemu page table entry and update hardware hash page table for the guest with correct write enable bit. With the above, for the first usage we should also check the savedwrite bit so that we can correctly clear the savedwite bit. For the later, we add a new variant __pte_write(). With this we can revert write_protect_page part of |

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.
