Hi Bob,

Why do you want to use FROM_CLIENT and TO_CLIENT suffix?
It seems readable to use FROM_USER and TO_USER suffix (i.e. between user space and kernel space).

The whole purpose of this patch is to extend the memory barriers to support
user <-> kernel *and* kernel <-> kernel. Changing the name made it clearer
that it's not just user space. It also made it easier to make sure I had
gotten all of them changed/looked at. Now that is done, if everyone wants it
back to USER I could be talked into it.
