The target_value field in struct pm_qos_constraints is used for lockless access to the effective constraint value of a given QoS list, so the readers of it cannot expect it to always reflect the most recent effective constraint value. However, they can and do expect it to be equal to a valid effective constraint value computed at a certain time in the past (event though it may not be the most recent one), so add READ|WRITE_ONCE() annotations around the target_value accesses to prevent the compiler from possibly causing that expectation to be unmet by generating code in an exceptionally convoluted way.

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.
