Keith Busch db0fd6b15b block: ensure iov_iter advances for added pages
[ Upstream commit 325347d965 ]

There are cases where a bio may not accept additional pages, and the iov
needs to advance to the last data length that was accepted. The zone
append used to handle this correctly, but was inadvertently broken when
the setup was made common with the normal r/w case.

Fixes: 576ed91354 ("block: use bio_add_page in bio_iov_iter_get_pages")
Fixes: c58c0074c5 ("block/bio: remove duplicate append pages code")

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.
