Subject: [PATCH net-next 0/4] splice, net: Replace sendpage with sendmsg(MSG_SPLICE_PAGES), part 2
Date: Wed, 24 May 2023 15:49:19 +0100 [thread overview]
Message-ID: <20230524144923.3623536-1-dhowells@redhat.com> (raw)
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:
