    Subject[PATCH 09/17] ocfs2: Don't snprintf() without a format.
    From: Joel Becker <>

    Some system files are per-slot. Their names include the slot number.
    ocfs2_sprintf_system_inode_name() uses the system inode definitions to
    fill in the slot number with snprintf().

    For global system files, there is no node number, and the name was
    printed as a format with no arguments. -Wformat-nonliteral and
    -Wformat-security don't like this. Instead, use a static "%s" format
    and the name as the argument.
