Hi Dan, Proposing the patch series to be merged via nvdimm tree as kindly agreed by you. We have ack/review on XFS, EXT4 & VIRTIO patches. Incorporated all the changes suggested in v8. This version added a new patch 4 for dax for device mapper change and some minor style changes in patch 2. Kept all the reviews. Request to please merge the series. --- This patch series has

This patch series has implementation for "virtio pmem". "virtio pmem" is fake persistent memory(nvdimm) in guest which allows to bypass the guest page cache. This also implements a VIRTIO based asynchronous flush mechanism. Sharing guest kernel driver in this patchset with the changes suggested in v4. Tested with Qemu side device emulation [6] for virtio-pmem.

This patch series is ready to be merged via nvdimm tree as discussed with Dan. We have ack/review on XFS, EXT4 & VIRTIO patches. Need an ack on device mapper change in patch 4. Mike, Can you please review and ack patch4. This version does not has any additonal code change from v10 and is only rebase of v10 on Linux 5.2-rc4 which is required for patch4. Keeping all the existing

Hi Michael & Dan, Please review/ack the patch series from LIBNVDIMM & VIRTIO side. We have ack on ext4, xfs patches(4, 5 & 6) patch 2. Still need your ack on nvdimm patches(1 & 3) & virtio patch 2. Changes done from v7 are only in patch(2 & 3) and not affecting existing reviews. Request to please review. ---- This patch series has implementation for "virtio

Hi Jens, this series removes the revalidate_disk() function, which has been a really odd duck in the last years. The prime reason why most people use it is because it propagates a size change from the gendisk to the block_device structure. But it also calls into the rather ill defined ->revalidate_disk method which is rather useless for the callers. So this adds a new helper to just

The race condition is noticed between disk_add() and disk attributes, on virtio-blk hotplug. Userspace listens to the KOBJ_ADD uevent generated in add_disk(). At that point we haven't created the serial attribute file, therefore depending on how fast udev reacts, the /dev/disk/by-id/ entry doesn't always get created. As pointed out by Christoph Hellwig in the specific fix [1], virtio-blk
