The reuseq is actually a recycle stack, only accessed from the kernel

Also, the implementation details of the stack should belong to the

Clean up and rename for consistency in preparation for the next
patch.

Prepare/swap is to cater to how drivers should be written - being able
to allocate resources independently of those currently used. Allowing
for changing ring sizes and counts on the fly. This patch makes it
harder to write drivers in the way we are encouraging people to.
IOW no, please don't do this.
The main reason I rewrote this was to provide the same type
of functionality as realloc() - no need to allocate/initialize a new
array if the old one would still end up being used. This would seem
to be a win for the typical case of having the interface go up/down.
Perhaps I should have named the function differently?
