Ming Lei fe2008640a block: don't protect generic_make_request_checks with blk_queue_enter
Now a063057d7c ("block: Fix a race between request queue removal and
the block cgroup controller") has been reverted, and blkcg_exit_queue()
won't be called in blk_cleanup_queue() any more.

So don't need to protect generic_make_request_checks() with
blk_queue_enter(), then the total mess can be cleaned.

37f9579f4c ("blk-mq: Avoid that submitting a bio concurrently with device
removal triggers a crash") is reverted.

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.
