Applied to for-next with the following fixup to make it bisectable:

    btrfs: build fixup for qgroup_account_snapshot

    The macro btrfs_std_error got renamed to btrfs_handle_fs_error in an
    independent branch for the same merge target (4.7). To make the code
    compilable for bisectability reasons, add a temporary stub.
