[openib-general] Question on : ib_reg_phys_mr()

[Devesh Sharma]

Thanks James for quick reply,

In your nfs-rdma context what this function is supposed to do?
I know that this function returns memory region, but what is the difference
from other mr returning functions?
why get_dma_mr can't be used?
