[BUG] We got some test failures related to btrfs-convert with subpage, e.g. btrfs/012, the failure would cause the following dmesg: BTRFS warning (device nvme0n1p7): v1 space cache is not supported for page size 16384 with sectorsize 4096 BTRFS error (device nvme0n1p7): open_ctree failed [CAUSE] v1 space cache has tons of hard coded PAGE_SIZE usage, and considering v2 space cache is going to replace it (which is already the new default since v5.15 btrfs-progs), thus for btrfs subpage support, we just simply reject the v1 space cache, and utilize v2 space cache when possible. But there is special catch in btrfs-convert, although we're specifying v2 space cache as the new default for btrfs-convert, it doesn't really follow the specification at all. Thus the converted filesystem will still go v1 space cache. [FIX] It can be a huge change to btrfs-convert to make the initial btrfs image to support v2 cache. Thus this patch would change the fs at the final stage, just before we finalize the btrfs. This patch would drop all the v1 cache created, then call btrfs_create_free_space_tree() to populate the free space tree and commit the superblock with needed compat_ro flags.
