Linus Torvalds ae3fa8bd73 - Fix bug in DM crypt's sizing of its block integrity tag space,
resulting in less memory use when DM crypt layers on DM integrity.
 
 - Fix a long-standing DM thinp crash consistency bug that was due to
   improper handling of FUA.  This issue is specific to writes that
   fill an entire thinp block which needs to be allocated.

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.
