  b703b31ea8cd22 (types: reuse common phys_vec type instead of DMABUF open‑coded variant)

interacting with commit:

  e6738fe6cad448 (RDMA/uverbs: Add DMABUF object type and operations)

from the rdma tree.  I have reverted the latter commit (it being the new
one), really a semantic fixup should be applied - I will try to revisit
tomorrow.
