[ Upstream commit748dc0b65e] Partial completions of zone append request is not allowed but if a zone append completion indicates a number of completed bytes different from the original BIO size, only the BIO status is set to error. This leads to bio_advance() not setting the BIO size to 0 and thus to not call bio_endio() at the end of req_bio_endio(). Make sure a partially completed zone append is failed and completed immediately by forcing the completed number of bytes (nbytes) to be equal to the BIO size, thus ensuring that bio_endio() is called.

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.
