Correction. The library wasn't dropped (by Red Hat anyway), we just
didn't use it ourselves (meaning it was not used by any software that we
shipped, but we still shipped it in case someone's out of box software
used it). We didn't drop it until rdma-core dropped it. I'm not sure
we can take this patch yet as the kernel should maintain backward
compatibility with older apps using the old library for at least some
period of time.
