Btrfs-progs: alloc our super copy in btrfs-find-root
Dave fixed the fs_info to allocate the super copy instead of embedding it, but he failed to notice that I open code open_ctree in btrfs-find-root so we end up with a super that's not allocated, so we segfault whenever you try to run btrfs-find-root. I've fixed this up and now we don't segfault anymore. Thanks, Signed-off-by: Josef Bacik <>
