Urrg. I wish we could just get out of the game of messing with block device inode settings from file systems. I guess doing it when using buffer_heads is hard, but file systems without buffer heads should have a way out of even propagating their block size to the block device inode. And file systems with buffer heads should probably not support large folios like this :P
