Hi, Question is pretty simple: "How to change node size and leaf size on previously created partition?" Now, I know what most people will say: "you should''ve be smarter while typing mkfs.btrfs". Well, I''m intending to convert in place ext4 partition but there seems to be no option for leaf and node size in this tool. If it''s not possible I guess

Hi, The following patches add support for ext4 and btrfs to PV-GRUB. These patches are taken nearly verbatim from those provided by Fedora and Gentoo.
