Thanks, but this is intentional to keep the patches obvious. Patch 27 adds and/or uses a local fs_info in every function that uses root->fs_info more than once. Unfortunately, the list seems to have dropped it. https://git.kernel.org/cgit/linux/kernel/git/jeffm/linux-btrfs.git/commit/?h=btrfs-testing/root-fsinfo-cleanup-squashed&id=b7bccd6c7a2ac810eca8109adcdb3647a776e7de It also dropped the patch that converts everything taking a root but not using it for anything other than an fs_info to fs_info. https://git.kernel.org/cgit/linux/kernel/git/jeffm/linux-btrfs.git/commit/?h=btrfs-testing/root-fsinfo-cleanup-squashed&id=9cd5ae906bbb22962091aaaaa7ff4e85b03ee26d -Jeff
