FMR's ro_unmap method is already synchronous because ib_unmap_fmr() is a synchronous verb. However, some improvements can be made here. 1. Gather all the MRs for the RPC request onto a list, and invoke ib_unmap_fmr() once with that list. This reduces the number of doorbells when there is more than one MR to invalidate 2. Perform the DMA unmap _after_ the MRs are unmapped, not before. This is critical after invalidating a Write chunk.
