Ik vermoed dat er niet veel zullen zijn die RDS daadwerkelijk gebruiken, dus je kan het veilig deactiveren met de geleverde workaround of simpelweg deactiveren in je kernel configuratie.
Voor wie zich af vraagt wat RDS is een quote uit de documentatie (Documentation/networking/rds.txt):
RDS provides reliable, ordered datagram delivery by using a single
reliable connection between any two nodes in the cluster. This allows
applications to use a single socket to talk to any other process in the
cluster - so in a cluster with N processes you need N sockets, in contrast
to N*N if you use a connection-oriented socket transport like TCP.
RDS is not Infiniband-specific; it was designed to support different
transports. The current implementation used to support RDS over TCP as well
as IB. Work is in progress to support RDS over iWARP, and using DCE to
guarantee no dropped packets on Ethernet, it may be possible to use RDS over
UDP in the future.
