By reading the UTP Transfer Request List Completion Notification Register, which is added in UFSHCI Ver 3.0, SW can easily get the compeleted transfer requests. Thus, SW can get rid of host lock, which is used to synchronize the tr_doorbell and outstanding_reqs, on transfer requests dispatch and completion paths. This can further benefit random read/write performance.

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.
