[ Upstream commit325347d965] 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") Signed-off-by: Keith Busch <kbusch@kernel.org> Link: https://lore.kernel.org/r/20220712153256.2202024-1-kbusch@fb.com Signed-off-by: Jens Axboe <axboe@kernel.dk> Signed-off-by: Sasha Levin <sashal@kernel.org>
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.
