James Smart 59c6e13ecd Remove hba lock from NVMET issue WQE.
Unnecessary lock is taken. ring lock should be sufficient to protect the
work queue submission.

This was noticed when doing performance testing. The hbalock is not
needed to issue io to the nvme work queue.

Linux kernel
============

This file was moved to Documentation/admin-guide/README.rst

Please notice that there are several guides for kernel developers and users.
These guides can be rendered in a number of formats, like HTML and PDF.

In order to build the documentation, use ``make htmldocs`` or
``make pdfdocs``.

There are various text files in the Documentation/ subdirectory,
several of them using the Restructured Text markup notation.
See Documentation/00-INDEX for a list of what is contained in each file.

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.
