The issue is when glibc and linux provide the same standards based API (eg in.h) - then the uapi version of in.h is really only for consumption by glibc and other very special cases. Forcing apps that need to access the rdma uapi that is not implemented in glibc to deal with that mess is what is problematic. The uapi system has a number of issues like this :| If you make it so I cannot include rdma_user_rxe.h and netinet/in.h, (for instance) in the same file then you broke user space use of the header and things are worse off..
