Further testing showed that the fix introduced in7dfb8be11b("btrfs: Round down values which are written for total_bytes_size") was insufficient and it could still lead to discrepancies between the total_bytes in the super block and the device total bytes. So this patch also ensures that the difference between old/new sizes when shrinking/growing is also rounded down. This ensure that we won't be subtracting/adding a non-sectorsize multiples to the superblock/device total sizees.

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.
