Now we only export hctx->type via sysfs, and there isn't such info in hctx entry under debugfs. We often use debugfs only to diagnose queue mapping issue, so add the support in debugfs. Queue mapping becomes a bit more complicated after multiple queue mapping is supported, we may write blktest to verify if queue mapping is valid based on blk-mq-debugfs. Given not necessary to export hctx->type twice, so remove the export from sysfs.

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.
