Coly Li 08ec1e6282 bcache: add io error counting in write_bdev_super_endio()
When backing device super block is written by bch_write_bdev_super(),
the bio complete callback write_bdev_super_endio() simply ignores I/O
status. Indeed such write request also contribute to backing device
health status if the request failed.

This patch checkes bio->bi_status in write_bdev_super_endio(), if there
is error, bch_count_backing_io_errors() will be called to count an I/O
error to dc->io_errors.

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.
