Pull device mapper fixes from Mike Snitzer: - Fix DM cache metadata to verify that a cache has block before trying to continue with operation that requires them. - Fix bio-based DM core's dm_make_request() to properly impose device limits on individual bios by making use of blk_queue_split(). - Fix long-standing race with how DM thinp notified userspace of thin-pool mode state changes before they were actually made. - Fix the zoned target's bio completion handling; this is a fairly invassive fix at this stage but it is localized to the zoned target. Any zoned target users will benefit from this fix. * tag 'for-4.20/dm-fixes' of git://git.kernel.org/pub/scm/linux/kernel/git/device-mapper/linux-dm: dm thin: bump target version dm thin: send event about thin-pool state change _after_ making it dm zoned: Fix target BIO completion handling dm: call blk_queue_split() to impose device limits on bios dm cache metadata: verify cache has blocks in blocks_are_clean_separate_dirty()
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.
