bio_clone_bioset(). Also fixes splitting bio that has integrity payload. - Three fixes related to properly validating DAX capabilities of a stacked DM device that will advertise DAX support. - Update DM writecache target to use 2-factor allocator arguments. Kees says this is the last related change for 4.18. - Fix DM zoned target to use GFP_NOIO to avoid triggering reclaim during IO submission (caught by lockdep). - Fix DM thinp to gracefully recover from running out of data space while a previous async discard completes (whereby freeing space). - Fix DM thinp's metadata transaction commit to avoid needless work. -----BEGIN PGP SIGNATURE----- Version: GnuPG v1 iQEcBAABAgAGBQJbNURXAAoJEMUj8QotnQNaPVYIAISzFYsSLEEYiGF5CDn2A07/ vd4TBIk7sAVQ/zouNGSNUHepoPJZR8E75SLO4lqZ214fyeYl9/48Za3dlyXeHldR ziCCYFyHKvKgfZpBpbO43HbZbWvcVplIAt+GhhXepHy9jJC7+XQzMOqGwcvK2pW4 qCOqLTLaTGdzx5UaoLCG2Yg3E1TrYH0kZei/WLRBGW12WAsCzqNqUsZ5TgeilxCt r/5ajPsXkcNjV9BrUNwY43J+WX8eKIuFKRSbnVdjHBEoVCeCwnP1R8WJnMm5/BTh KZpyYTlFsBZ+Gvzojt2XI80ttviXtSUoJJNZgze9JT2xR4jMfn4yFQr/odxJucE= =ZGTy -----END PGP SIGNATURE----- Merge tag 'for-4.18/dm-fixes' of git://git.kernel.org/pub/scm/linux/kernel/git/device-mapper/linux-dm Pull device mapper fixes from Mike Snitzer: - Fix dm core to use more efficient bio_split() instead of bio_clone_bioset().

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.
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.
