MSG_SPLICE_PAGES is an internal hint that tells the protocol that it should splice the pages supplied if it can. Its sendpage implementation is then turned into a wrapper around that. Does anyone actually use AF_KCM? Upstream it has some issues. It doesn't seem able to handle a "message" longer than 113920 bytes without jamming and doesn't handle the client termination once it is jammed.
