Jakub Kicinski 9ae440b8fd Merge branch 'splice-net-switch-over-users-of-sendpage-and-remove-it'
David Howells says:

====================
splice, net: Switch over users of sendpage() and remove it

Here's the final set of patches towards the removal of sendpage.  All the
drivers that use sendpage() get switched over to using sendmsg() with
MSG_SPLICE_PAGES.

The following changes are made:

 (1) Make the protocol drivers behave according to MSG_MORE, not
     MSG_SENDPAGE_NOTLAST.  The latter is restricted to turning on MSG_MORE
     in the sendpage() wrappers.

 (2) Fix ocfs2 to allocate its global protocol buffers with folio_alloc()
     rather than kzalloc() so as not to invoke the !sendpage_ok warning in
     skb_splice_from_iter().

 (3) Make ceph/rds, skb_send_sock, dlm, nvme, smc, ocfs2, drbd and iscsi
     use sendmsg(), not sendpage and make them specify MSG_MORE instead of
     MSG_SENDPAGE_NOTLAST.

 (4) Kill off sendpage and clean up MSG_SENDPAGE_NOTLAST.

README

Linux kernel
============

There are several guides for kernel developers and users. These guides can
be rendered in a number of formats, like HTML and PDF. Please read
Documentation/admin-guide/README.rst first.

In order to build the documentation, use ``make htmldocs`` or
``make pdfdocs``.  The formatted documentation can also be read online at:

    https://www.kernel.org/doc/html/latest/

There are various text files in the Documentation/ subdirectory,
several of them using the Restructured Text markup notation.

Please read the Documentation/process/changes.rst file, as it contains the
requirements for building and running the kernel, and information about
the problems which may result by upgrading your kernel.
