-Subject: [PATCH] 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.
