In order to provide a better way to do subpage blocksizes we need to stop allocating pages from a per fs btree inode and instead allocate our own pages. This work depends on 3 generic patches that I've sent previously remove mapping from balance_dirty_pages*() writeback: allow for dirty metadata accounting writeback: introduce super_operations->write_metadata This is a pretty big change but ultimately makes extent_buffer reclaim much cleaner and will make the sub-pagesize blocksize work significantly cleaner. I've been hammering on this for a few weeks now and seems to be pretty solid.
