To improve responsiveness, yield the FPU (temporarily re-enabling preemption) every 4 KiB encrypted/decrypted, rather than keeping preemption disabled during the entire encryption/decryption operation. Alternatively we could do this for every skcipher_walk step, but steps may be small in some cases, and yielding the FPU is expensive on x86.

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.
