From mboxrd@z Thu Jan 1 00:00:00 1970 From: "Michael S.

Not a regression - these previously simply didn't have vhost at all. Also, there's some DMA API code in the vdpa simulator is hacky - if no solution surfaces soon we can always disable it before release: it's not a big deal either way as it's just test code. The following changes since commit 16fbf79b0f83bc752cee8589279f1ebfe57b3b6e: Linux 5.6-rc7 (2020-03-22 18:31:56 -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 c9b9f5f8c0f3cdb893cb86c168cdaa3aa5ed7278: vdpa: move to drivers/vdpa (2020-04-02 10:41:40 -0400) ---------------------------------------------------------------- virtio: fixes, vdpa Some bug fixes.
