[PATCH net-next 0/4] splice, net: Replace sendpage with sendmsg(MSG_SPLICE_PAGES), part 2

From: David Howells
Date: Wed May 24 2023 - 10:50:33 EST

Here's the second tranche of patches towards providing a MSG_SPLICE_PAGES
internal sendmsg flag that is intended to replace the ->sendpage() op with
calls to sendmsg(). MSG_SPLICE_PAGES is a hint that tells the protocol
that it should splice the pages supplied if it can and copy them if not.

This set consists of the following parts:

(1) Implement MSG_SPLICE_PAGES support in Chelsio TLS and make
chtls_sendpage() just a wrapper around sendmsg().

(2) Implement MSG_SPLICE_PAGES support in AF_KCM and make kcm_sendpage()
just a wrapper around sendmsg().

I've pushed the patches here also:
