There is a limit that batched queue_rqs() can't work on shared tags queue, since the account of active requests can't be done there. Now we account the active requests only in blk_mq_get_driver_tag(), which is not the time we get driver tag actually (with none elevator). To support batched queue_rqs() on shared tags queue, we move the account of active requests to where we get the driver tag: 1. none elevator: blk_mq_get_tags() and blk_mq_get_tag() 2. other elevator: __blk_mq_alloc_driver_tag() This is clearer and match with the unaccount side, which just happen when we put the driver tag. The other good point is that we don't need RQF_MQ_INFLIGHT trick anymore, which used to avoid double account of flush request. Now we only account when actually get the driver tag, so all is good. We will remove RQF_MQ_INFLIGHT in the next patch.

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.
