Block core warned that discard_granularity was 0 for dm-raid with
personality of raid1. Reason is that raid_io_hints() was incorrectly
special-casing raid1 rather than raid0.
Fix raid_io_hints() by removing discard limits settings for
raid1. Check for raid0 instead.
Fixes: 61697a6abd ("dm: eliminate 'split_discard_bios' flag from DM target interface")

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.
