You are right, I am remembering an older version of the API (which I
still like better, obviously ;) ). I also see the problems each choice
of API can cause. I think the current API is the more reasonable
choice. I have adjusted XPMEM to keep a copy of the mm_struct pointer
at register time with my own accompanying inc of mm_count and likewise
do the unregister and mmdrop(); This resolved my problem.
Sorry for the noise.
Andrew, could you throw this patch as away as quickly as possible.
Sorry for wasting your time.
Thanks,
Robin
