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

Posted by David Howells 2 years, 6 months ago

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:
