Currently, libata ignores requests RQF_QUIET flag and print error messages for failed commands, regardless if this flag is set in the command request. Fix this by introducing the ata_eh_quiet() function and using this function in ata_eh_link_autopsy() to determine if the EH context should be quiet. This works by counting the number of failed commands and the number of commands with the quiet flag set. If both numbers are equal, the the EH context can be set to quiet and all error messages suppressed. Otherwise, only the error messages for the failed commands are suppressed and the link Emask and irq_stat messages printed.

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.
