Linus Torvalds 4ed7bdc1eb - Eliminate a couple indirect calls from bio-based DM core.
- Fix DM to allow reads that exceed readahead limits by setting io_pages
   in the backing_dev_info.
 
 - A couple code cleanups in request-based DM.
 
 - Fix various DM targets to check for device sector overflow if
   CONFIG_LBDAF is not set.
 
 - Use u64 instead of sector_t to store iv_offset in DM crypt; sector_t
   isn't large enough on 32bit when CONFIG_LBDAF is not set.
 
 - Performance fixes to DM's kcopyd and the snapshot target focused on
   limiting memory use and workqueue stalls.
 
 - Fix typos in the integrity and writecache targets.
 
 - Log which algorithm is used for dm-crypt's encryption and
   dm-integrity's hashing.
 
 - Fix false -EBUSY errors in DM raid target's handling of check/repair
   messages.
 
 - Fix DM flakey target's corrupt_bio_byte feature to reliably corrupt
   the Nth byte in a bio's payload.

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.
