Hello:

This series was applied to netdev/net-next.git (main)

Here are patches to make AF_KCM handle the MSG_SPLICE_PAGES internal
sendmsg flag.  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.

Here is the summary with links:
  - [net-next,v2,1/2] kcm: Support MSG_SPLICE_PAGES

  - [net-next,v2,2/2] kcm: Convert kcm_sendpage() to use MSG_SPLICE_PAGES

You are awesome, thank you!
