Mikulas Patocka b858a36fe9 bio-integrity: don't restrict the size of integrity metadata 
bio_integrity_add_page restricts the size of the integrity metadata to
queue_max_hw_sectors(q). This restriction is not needed because oversized
bios are split automatically. This restriction causes problems with
dm-integrity 'inline' mode - if we send a large bio to dm-integrity and
the bio's metadata are larger than queue_max_hw_sectors(q),
bio_integrity_add_page fails and the bio is ended with BLK_STS_RESOURCE
error.

An example that triggers it:

dd: error writing '/dev/mapper/in2': Cannot allocate memory
1+0 records in
0+0 records out
0 bytes copied, 0.00169291 s, 0.0 kB/s

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 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.
