While handling hwpoison in a THP page, it is possible that try_to_split_thp_page() fails. For example, when the THP page has been RDMA pinned. At this point, the kernel cannot isolate the poisoned THP page, all it could do is to send a SIGBUS to the user process with meaningful payload to give user-level recovery a chance.

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.
