Hi Linus, please pull from:
git://git.kernel.org/pub/scm/linux/kernel/git/nvdimm/nvdimm
tags/libnvdimm-for-5.3
...to receive primarily just the virtio_pmem driver for v5.3-rc1. The
lateness is attributed to me being out last week, and a last minute
regression hunt in a pending fix / rework of libnvdimm locking. Those
fixes can wait to post-rc1.
These commits have been in multiple -next releases, and uncovered a
late sparse fixup that is appended. The touches to ext4 and xfs have
received acks. Ted's ack is here [1], it arrived after I cut the
branch. Mike reviewed the device-mapper touches.

virtio_pmem: fix sparse warning (2019-07-16 19:44:26 -0700)
----------------------------------------------------------------
- virtio_pmem: The new virtio_pmem facility introduces a paravirtualized
persistent memory device that allows a guest VM to use DAX mechanisms to
access a host-file with host-page-cache. It arranges for MAP_SYNC to
be disabled and instead triggers a host fsync() when a 'write-cache
flush' command is sent to the virtual disk device.
- Miscellaneous small fixups.
