Under upstream staging commit5a2ca43fa5, the list handling code in kiblnd_handle_early_rxs() got changed to list_for_each_safe(). That protects against the current thread from deleting the current entry it is looking at. It does not protect against another thread from deleting the next item in the list (which the tmp variable points to). The way this routine holds then releases a lock opens the door to other threads doing just that. This patch reverts this commit on this routine.

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.
See Documentation/00-INDEX for a list of what is contained in each file.
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.
