The soft hwpoison injector via madvise(MADV_HWPOISON) operates in a synchrous way in a sense, the injector is also a process under test, and should it have the poisoned page mapped in its address space, it should get killed as much as in a real UE situation. Doing so align with what the madvise(2) man page says: " "This operation may result in the calling process receiving a SIGBUS and the page being unmapped."

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.
