Hi Paul!

I know you are currently looking at documentation of urcu data
structures. I did quite a bit of work in that area these past days. Here
is my plan:

1) I would like to deprecate, at some point, rculfqueue, wfqueue, and

2) For wfqueue, we replace it by wfcqueue, currently in the urcu master

3) For rculfstack, we replace it by lfstack available here (volatile

branch: urcu/lfstack

4) I did documentation improvements (and implemented pop_all as well as
   empty, and iterators) for wfstack here (volatile branch too):

branch: urcu/wfstack

5) The last one to look into would be rculfqueue. I'd really like to
   create a lfcqueue derived from wfcqueue if possible. It's the next
   item on my todo list this weekend.

Thoughts ?
