    Subjectquestions about native alpha futex implementation
    Hi,

    Alpha uses a generic futex implementation, which causes some problems [1].

    I've read through the code, and it appears as if the implementation
    could be done by using the ldq_l/stq_c instructions, relatively easy I
    might add. I'm definitely interested in implementing this, but first...

    I have only a few questions.

    1) What are the benefits of a native futex implementation, other than
    fixing the glibc test failures?
    2) Is there a technical reason it hasn't been implemented on Alpha?
    3) Am in correct that it could be done with ldq_l/stq_c instructions?

    I'm not experienced with kernel development, but I'd like to learn, so
    please bear with me.

    Thanks,

    Matt Turner
