CONFIG_FS_BTRFS=y
CONFIG_CMD_BTRFS=y

It's build off of the generic commands: CONFIG_CMD_FS_GENERIC so you
can use the generic "load" commands..

I did have to get a little creative as the load command uses ext
first, and so it would annoying print out this non-error:


diff --git a/fs/ext4/ext4_common.c b/fs/ext4/ext4_common.c
index dac9545365..a8e6fdef51 100644
--- a/fs/ext4/ext4_common.c
+++ b/fs/ext4/ext4_common.c
@@ -2378,7 +2378,7 @@ int ext4fs_mount(unsigned part_length)

  return 1;
 fail:
- printf("Failed to mount ext2 filesystem...\n");
+ //printf("Failed to mount ext2 filesystem...\n");
  free(data);
  ext4fs_root = NULL;
