uprobe/uretprobe tests don't do any validation of arguments/return values, and without this we can't be sure we are attached to the right function, or that we are indeed attached to a uprobe or uretprobe. To fix this record argument and return value for auto-attached functions and ensure these match expectations. Also need to filter by pid to ensure we do not pick up stray malloc()s since auto-attach traces libc system-wide.

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.
