[ Upstream commit b81e286ba1 ]
As algorithm testing is carried out without holding the main crypto
lock, it is always possible for the algorithm to go away during the
test.
So before crypto_alg_tested updates the status of the tested alg,
it checks whether it's still on the list of all algorithms. This
is inaccurate because it may be off the main list but still on the
list of algorithms to be removed.
Updating the algorithm status is safe per se as the larval still
holds a reference to it. However, killing spawns of other algorithms
that are of lower priority is clearly a deficiency as it adds
unnecessary churn.
Fix the test by checking whether the algorithm is dead.

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.
