benefit both the DM thinp and cache targets. - A few small DM kcopyd efficiency improvements. - Significant zoned related block core, DM core and DM zoned target changes that culminate with adding zoned append emulation (which is required to properly fix DM crypt's zoned support). - Various DM writecache target changes that improve efficiency. Adds an optional "metadata_only" feature that only promotes bios flagged with REQ_META. But the most significant improvement is writecache's ability to pause writeback, for a confiurable time, if/when the working set is larger than the cache (and the cache is full) -- this ensures performance is no worse than the slower origin device. -----BEGIN PGP SIGNATURE----- iQEzBAABCAAdFiEEJfWUX4UqZ4x1O2wixSPxCi2dA1oFAmDcpWgACgkQxSPxCi2d A1pD0AgAmySdpJxQBzBMOqnKaClErfxiWXDtvzBxFupG/jmqaN/k/kCFdKyDk89M 9r2rlv4+teZReEGjqjJ0umQgbX62x5y6f7vy4CeoE/+EQAUiZYXNARW8Uubu/Sgy mmvsgAdiuJqfJCX5TiQDwZIdll/QV8isteddMpOdrdM0fpCNlTvRao4S9UE2Rfni fPoPu7KNGDhKORvy/NloYFSHuxTaOSv6A44z15T2SoXPw9hLloFoXegE9Vrcfr/j gwLX3ponp4+K91BzPWz0QIQ7Wh+7O4xrmcXtBIvuIGNcfV+oGMZMtq/zEX8T6sDh GDlclxh/76iGgvINAQ437mXBINbPYQ== =8dUv -----END PGP SIGNATURE----- Merge tag 'for-5.14/dm-changes' of git://git.kernel.org/pub/scm/linux/kernel/git/device-mapper/linux-dm Pull device mapper updates from Mike Snitzer: - Various DM persistent-data library improvements and fixes that benefit both the DM thinp and cache targets. - A few small DM kcopyd efficiency improvements. - Significant zoned related block core, DM core and DM zoned target changes that culminate with adding zoned append emulation (which is required to properly fix DM crypt's zoned support). - Various DM writecache target changes that improve efficiency.

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.
