Pull libnvdimm fixes from Dan Williams: "The largest change is for a regression that landed during -rc1 for block-device read-only handling. Vaibhav found a new use for the ability (originally introduced by virtio_pmem) to call back to the platform to flush data, but also found an original bug in that implementation. Lastly, Arnd cleans up some compile warnings in dax. This has all appeared in -next with no reported issues. Summary: - Fix a regression of read-only handling in the pmem driver - Fix a compile warning - Fix support for platform cache flush commands on powerpc/papr" * tag 'libnvdimm-fixes-for-5.12-rc8' of git://git.kernel.org/pub/scm/linux/kernel/git/nvdimm/nvdimm: libnvdimm/region: Fix nvdimm_has_flush() to handle ND_REGION_ASYNC libnvdimm: Notify disk drivers to revalidate region read-only dax: avoid -Wempty-body warnings
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.
