Not sure anyone would ever want to run this code on 32-bit boxes, but
I'm a bit worried if wr_id is a 64-bit value, and we encode it into a
32-bit pointer, you'd always lose the top 32-bits.


Hey Dave,

This was addressed in: http://marc.info/?l=linux-rdma&m=141448978030924&w=2 (part of iser fixes for 3.18-rc).

Thanks!

Sagi.
