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.
