When btrfs fails the checksum check, it'll fill the whole page with "1". However, if %csum_expected is 0 (which means there is no checksum), then for some unknown reason, we just pretend that the read is correct, so userspace would be confused about the dilemma that read is successful but getting a page with all content being "1". This can happen due to a bug in btrfs-convert. This fixes it by always returning errors if checksum doesn't match.

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.
