The new qTimestamp attribute was added to UFS 4.0 spec, in order to synchronize timestamp between device logs and the host. The spec recommends to send this attribute upon device power-on Reset/HW reset or when switching to Active state (using SSU command). Due to this attribute, the attribute's max value was extended to 8 bytes. As a result, the new definition of struct utp_upiu_query_v4_0 was added.

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.
