Currently free space cache inode size is determined by two factors: - block group size - PAGE_SIZE This means, for the same sized block groups, with different PAGE_SIZE, it will result in different inode sizes. This will not be a good thing for subpage support, so change the requirement for PAGE_SIZE to sectorsize. Now for the same 4K sectorsize btrfs, it should result the same inode size no matter what the PAGE_SIZE is. Signed-off-by: Qu Wenruo <wqu@suse.com> Signed-off-by: David Sterba <dsterba@suse.com>
Linux kernel ============ There are several guides for kernel developers and users. These guides can be rendered in a number of formats, like HTML and PDF. Please read Documentation/admin-guide/README.rst first. In order to build the documentation, use ``make htmldocs`` or ``make pdfdocs``. The formatted documentation can also be read online at: https://www.kernel.org/doc/html/latest/ There are various text files in the Documentation/ subdirectory, several of them using the Restructured Text markup notation. 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.
