Shared queues are likely to receive I/O at a high rate. This may deceptively let them be considered as wakers of other queues. But a false waker will unjustly steal bandwidth to its supposedly woken queue. So considering also shared queues in the waking mechanism may cause more control troubles than throughput benefits. This commit keeps shared queues out of the waker-detection mechanism.

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.
