In general please don't fix two types of issues in the same patch. Also, as 
to the unsinged -> unsigned int, the linux-rdma maintainer has already said 
we don't really want all of the code churn for this [1].

I suggest to respin this patch with just the ACCESS_ONCE->READ_ONCE change 
so that can be reviewed on it's own.

Same response [1] as to your previous patch. If you do spin the READ_ONCE 
bit please squash the two.
