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.

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. ---------------------------------------------------------------- Andy Shevchenko (1): libnvdimm, namespace: Drop uuid_t implementation detail Pankaj Gupta (8): libnvdimm: nd_region flush callback support virtio-pmem: Add virtio pmem driver libnvdimm: add dax_dev sync flag dm: enable synchronous dax dax: check synchronous mapping is supported ext4: disable map_sync for async flush xfs: disable map_sync for async flush virtio_pmem: fix sparse warning drivers/acpi/nfit/core.c | 4 +- drivers/dax/bus.c | 2 +- drivers/dax/super.c | 19 +++++- drivers/md/dm-table.c | 24 ++++++-- drivers/md/dm.c | 5 +- drivers/md/dm.h | 5 +- drivers/nvdimm/Makefile | 1 + drivers/nvdimm/claim.c | 6 +- drivers/nvdimm/namespace_devs.c | 8 +-- drivers/nvdimm/nd.h | 1 + drivers/nvdimm/nd_virtio.c | 125 +++++++++++++++++++++++++++++++++++++++ drivers/nvdimm/pmem.c | 18 ++++-- drivers/nvdimm/region_devs.c | 33 ++++++++++- drivers/nvdimm/virtio_pmem.c | 122 ++++++++++++++++++++++++++++++++++++++ drivers/nvdimm/virtio_pmem.h | 55 +++++++++++++++++ drivers/s390/block/dcssblk.c | 2 +- drivers/virtio/Kconfig | 11 ++++ fs/ext4/file.c | 10 ++-- fs/xfs/xfs_file.c | 9 ++- include/linux/dax.h | 41 ++++++++++++- include/linux/libnvdimm.h | 10 +++- include/uapi/linux/virtio_ids.h | 1 + include/uapi/linux/virtio_pmem.h | 34 +++++++++++ 23 files changed, 508 insertions(+), 38 deletions(-) create mode 100644 drivers/nvdimm/nd_virtio.c create mode 100644 drivers/nvdimm/virtio_pmem.c create mode 100644 drivers/nvdimm/virtio_pmem.h create mode 100644 include/uapi/linux/virtio_pmem.h
