questions about native alpha futex implementation

[Matt Turner]

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
