    Hi all,
    (I'm sorry for the very late comment.)

    I think this patch set is a great step to get the Linux system
    reliable close to mainframe. I really appreciate your work.

    I believe people concerning high reliable system are expecting
    this kind of functionality.
    But I wonder why this patch set (including former MCE improvements
    patches) has not been merged into any subsystem trees yet.
    What is the problem? Because of the deadlock bug and the ref counter
    problem? Or are we waiting for 32bit unification to complete?
    If so, I'd like to try to narrow down the problems or review
    patches (although I'm afraid I'm not so skillful).

    BTW, I looked over this patch set, and I couldn't
    find any problems except for one minor point. I'll post
    a comment about it later. It is very late, but better than nothing.

    Regards,
