Linus Torvalds 7a771ceac7 - Fix dm-raid transient device failure processing and other smaller
tweaks.
 
 - Add journal support to the DM raid target to close the 'write hole' on
   raid 4/5/6.
 
 - Fix dm-cache corruption, due to rounding bug, when cache exceeds 2TB.
 
 - Add 'metadata2' feature to dm-cache to separate the dirty bitset out
   from other cache metadata.  This improves speed of shutting down
   a large cache device (which implies writing out dirty bits).
 
 - Fix a memory leak during dm-stats data structure destruction.
 
 - Fix a DM multipath round-robin path selector performance regression
   that was caused by less precise balancing across all paths.
 
 - Lastly, introduce a DM core fix for a long-standing DM snapshot
   deadlock that is rooted in the complexity of the device stack used in
   conjunction with block core maintaining bios on current->bio_list to
   manage recursion in generic_make_request().  A more comprehensive fix
   to block core (and its hook in the cpu scheduler) would be wonderful
   but this DM-specific fix is pragmatic considering how difficult it has
   been to make progress on a generic fix.

Linux kernel
============

This file was moved to Documentation/admin-guide/README.rst

Please notice that there are several guides for kernel developers and users.
These guides can be rendered in a number of formats, like HTML and PDF.

In order to build the documentation, use ``make htmldocs`` or
``make pdfdocs``.

There are various text files in the Documentation/ subdirectory,
several of them using the Restructured Text markup notation.
See Documentation/00-INDEX for a list of what is contained in each file.

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.
