+Subject: rdma: sync some IP headers with glibc
+
+In the commit 9a362cc71a45, new userspace header:
+  (i.e rdma/rdma_user_cm.h -> linux/in6.h)
+is included before the kernel space header:
+  (i.e utils.h -> resolv.h -> netinet/in.h).
+
+This leads to unsynchronous some IP headers and compiler got failure
+with error: redefinition of some structs IP.
+
+In this commit, just reorder this including to make them in-sync.
