Linus Torvalds 2a89b99f58 - A request-based DM fix to not use a waitqueue to wait for blk-mq IO
completion because doing so is racey.
 
 - A couple more DM zoned target fixes to address issues introduced
   during the 5.8 cycle.
 
 - A DM core fix to use proper interface to cleanup DM's static flush
   bio.
 
 - A DM core fix to prevent mm recursion during memory allocation
   needed by dm_kobject_uevent.

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.
