Jinyoung Choi 14a1b55482 bio-integrity: create multi-page bvecs in bio_integrity_add_page() 
[ Upstream commit 0ece1d649b ]

In general, the bvec data structure consists of one for physically
continuous pages. But, in the bvec configuration for bip, physically
continuous integrity pages are composed of each bvec.

Allow bio_integrity_add_page() to create multi-page bvecs, just like
the bio payloads. This simplifies adding larger payloads, and fixes
support for non-tiny workloads with nvme, which stopped using
scatterlist for metadata a while ago.

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.
