As I said in the comments on v1, do we have any actual numbers on how
long the bind step takes? From memory, you could bind ~32GB in a
single bind h-call before phyp would hit it's time limit of 250us and
return a continue token. Assuming that holds we'll be saving a few
dozen milliseconds at best.

      if (rc)
              goto err;

I am also not sure about the module reference count here. Should we
increment the module reference count after a bind so that we can track
failures in ubind and fail the module unload?

I don't really get what you're concerned about here. The error
handling path calls drc_pmem_unbind() so if there's a bind error we
should never leave probe with memory still bound.

In the remove callback, if the ubind fail should we allow the module
unload?
