Ewan D. Milne 5a1d7bb7d3 scsi: sd: Suppress spurious errors when WRITE SAME is being disabled 
[ Upstream commit e5cc9002ca ]

The block layer code will split a large zeroout request into multiple bios
and if WRITE SAME is disabled because the storage device reports that it
does not support it (or support the length used), we can get an error
message from the block layer despite the setting of RQF_QUIET on the first
request.  This is because more than one request may have already been
submitted.

Fix this by setting RQF_QUIET when BLK_STS_TARGET is returned to fail the
request early, we don't need to log a message because we did not actually
submit the command to the device, and the block layer code will handle the
error by submitting individual write bios.

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.

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.
