integrity_kernel_read() can fail in which case we forward to call ahash_request_free() on a currently running request. We have to wait for its completion before we can free the request. This was observed by interrupting a "find / -type f -xdev -print0 | xargs -0 cat 1>/dev/null" with ctrl-c on an IMA enabled filesystem.

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.
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.
