With newly merged code the uprobe behaviour is slightly different and affects uprobe consumer test. We no longer need to check if the uprobe object is still preserved after removing last uretprobe, because it stays as long as there's pending/installed uretprobe instance. This allows to run uretprobe consumers registered 'after' uprobe was hit even if previous uretprobe got unregistered before being hit. The uprobe object will be now removed after the last uprobe ref is released and in such case it's held by ri->uprobe (return instance) which is released after the uretprobe is hit.

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 reStructuredText 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.
