    Okay, but with this patch applied, we will just ignore rtas region, right?
    Thus, when I echo 0 to free all the 128M crashkernel memory, the final
    result will be 32M left, which means crash_size will still show 32M.
    This looks odd.

    How about skipping the 32M as a whole? I mean once the region being freed
    has overlap with this rtas region, skip the whole rtas region, and let
    crash_size
    show 0?

    Thanks.
