This patch set complete the cleanup done in the driver/verbs/uverbs
where the dependency of the code in the ib_x uobject pointer was
removed.
The uobject pointer is removed from the ib_pd as last step
before I can start adding the pd sharing code.
The rdma/netlink code now don't have dependency in the ib_pd
uobject pointer and can report multiple context id that point
to same ib_pd.
Using iproute2 I can test the modified rdma/netlink:
[root@qemu-fc29 iproute2]# ./rdma/rdma res show pd
dev mlx4_0 pdn 0 local_dma_lkey 0x8000 users 4 comm [ib_core]
dev mlx4_0 pdn 1 local_dma_lkey 0x8000 users 4 comm [ib_core]
dev mlx4_0 pdn 2 local_dma_lkey 0x8000 users 5 comm [ib_ipoib]
dev mlx4_0 pdn 3 local_dma_lkey 0x8000 users 5 comm [ib_ipoib]
dev mlx4_0 pdn 4 local_dma_lkey 0x8000 users 0 comm [ib_srp]
dev mlx4_0 pdn 5 local_dma_lkey 0x8000 users 0 comm [ib_srpt]
dev mlx4_0 pdn 14 local_dma_lkey 0x0 users 2 ctxn 8 pid 11786 comm ib_write_bw
dev mlx4_0 pdn 15 local_dma_lkey 0x0 users 2 ctxn 9 pid 11787 comm ib_write_bw
