The sectorsize member of btrfs_block_group_cache is unused. So remove it, this reduces the number of holes in the struct. With patch: /* size: 856, cachelines: 14, members: 40 */ /* sum members: 837, holes: 4, sum holes: 19 */ /* bit holes: 1, sum bit holes: 29 bits */ /* last cacheline: 24 bytes */ Without patch: /* size: 864, cachelines: 14, members: 41 */ /* sum members: 841, holes: 5, sum holes: 23 */ /* bit holes: 1, sum bit holes: 29 bits */ /* last cacheline: 32 bytes */ Signed-off-by: Nikolay Borisov <nborisov@suse.com> Reviewed-by: David Sterba <dsterba@suse.com> Signed-off-by: David Sterba <dsterba@suse.com>
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.
