Currently we show the hctx.active value for the per-hctx "active" file.
However this is not maintained for shared tags, and we instead keep a
record of the number active requests per request queue - see commit
f1b49fdc1c64 ("blk-mq: Record active_queues_shared_sbitmap per tag_set for
when using shared sbitmap).
Change for the case of shared tags to show the active requests per request
queue by using __blk_mq_active_requests() helper.

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.
