Currently _drbd_send_page() use sendpage_ok() in order to enable MSG_SPLICE_PAGES, it check the first page of the iterator, the iterator may represent contiguous pages. MSG_SPLICE_PAGES enables skb_splice_from_iter() which checks all the pages it sends with sendpage_ok(). When _drbd_send_page() sends an iterator that the first page is sendable, but one of the other pages isn't skb_splice_from_iter() warns and aborts the data transfer. Using the new helper sendpages_ok() in order to enable MSG_SPLICE_PAGES solves the issue.

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 reStructuredText 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.
