commit e053aaf4da56cbf0afb33a0fda4a62188e2c0637 upstream. This is actually an older issue, but we never used to hit the -EAGAIN path before having done sb_start_write(). Make sure that we always call kiocb_end_write() if we need to retry the write, so that we keep the calls to sb_start_write() etc balanced.

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.
