I have noticed this remark in the wiki: https://btrfs.wiki.kernel.org/index.php/Project_ideas#Different_sector_sizes and the WIP patch there. Can someone please update what is the status on this? Is someone working on it? I can suggest to try and pick this up, if people are interested in this solution. Regards Ronen Shitrit
