Christoph Hellwig 5407334c53 block-crypto-fallback: use a bio_set for splitting bios
bio_split with a NULL bs argumen used to fall back to kmalloc the
bio, which does not guarantee forward progress and could to deadlocks.
Now that the overloading of the NULL bs argument to bio_alloc_bioset
has been removed it crashes instead.  Fix all that by using a special
crafted bioset.

README

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.
