Reference counting of multicast memberships is maintained by the kernel. The rdma_cm will track join/leave requests correctly. The mentioned issue only applies to applications that send their own MADs directly to the SA (i.e. use the umad interface). - Sean -- To unsubscribe from this list: send the line "unsubscribe linux-rdma" in the body of a message to [email protected] More majordomo info at http://vger.kernel.org/majordomo-info.html
