Introduce read-write instrumentation hooks, to more precisely denote an operation's behaviour. KCSAN is able to distinguish compound instrumentation, and with the new instrumentation we then benefit from improved reporting. More importantly, read-write compound operations should not implicitly be treated as atomic, if they aren't actually atomic.

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.
