Most exciting stuff this time around has to do with performance. The following changes since commit 6a8f57ae2eb07ab39a6f0ccad60c760743051026: Linux 6.3-rc7 (2023-04-16 15:23:53 -0700) are available in the Git repository at: https://git.kernel.org/pub/scm/linux/kernel/git/mst/vhost.git tags/for_linus for you to fetch changes up to c82729e06644f4e087f5ff0f91b8fb15e03b8890: vhost_vdpa: fix unmap process in no-batch mode (2023-04-21 03:02:36 -0400) ---------------------------------------------------------------- virtio,vhost,vdpa: features, fixes, cleanups reduction in interrupt rate in virtio perf improvement for VDUSE scalability for vhost-scsi non power of 2 ring support for packed rings better management for mlx5 vdpa suspend for snet VIRTIO_F_NOTIFICATION_DATA shared backend with vdpa-sim-blk user VA support in vdpa-sim better struct packing for virtio fixes, cleanups all over the place Signed-off-by: Michael S.
