Coly Li 09a44ca211 bcache: use pr_info() to inform duplicated CACHE_SET_IO_DISABLE set
It is possible that multiple I/O requests hits on failed cache device or
backing device, therefore it is quite common that CACHE_SET_IO_DISABLE is
set already when a task tries to set the bit from bch_cache_set_error().
Currently the message "CACHE_SET_IO_DISABLE already set" is printed by
pr_warn(), which might mislead users to think a serious fault happens in
source code.

This patch uses pr_info() to print the information in such situation,
avoid extra worries. This information is helpful to understand bcache
behavior in cache device failures, so I still keep them in source code.

Fixes: 771f393e8f ("bcache: add CACHE_SET_IO_DISABLE to struct cache_set flags")

README

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.
See Documentation/00-INDEX for a list of what is contained in each file.

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.
