Write Zeroes sets PRACT when block integrity is enabled (as it should), but neglects to also set the reftag which is expected by reads. This causes protection errors on reads. Fix this by setting the reftag for type 1 and 2 (for type 3, reads will not check the reftag). Signed-off-by: Klaus Jensen <k.jensen@samsung.com> Reviewed-by: Martin K.

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.
