A driver should not be making this call. See the openib-general mailing list archive for a detailed description on how a driver can avoid making this call, for one such example of fixing a driver to not do this.

I don't see a detailed description of a solution in the mailing list archives. I've been following the Inifiniband driver development, and all I see are the same problems, but no solutions. People say we need to use get_user_pages(), but that function doesn't support overlapping memory regions.
