Thank you!
The biggest thing here is the adminq change - but it looks like the only way to avoid headq blocking causing indefinite stalls. The following changes since commit 6c85d6b653caeba2ef982925703cbb4f2b3b3163: virtio: rename virtio_find_vqs_info() to virtio_find_vqs() (2024-07-17 05:20:58 -0400) 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 6d834691da474ed1c648753d3d3a3ef8379fa1c1: virtio_pci_modern: remove admin queue serialization lock (2024-07-17 05:43:21 -0400) ---------------------------------------------------------------- virtio: fixes This fixes 3 issues: - prevent admin commands on one VF blocking another: fixes a huge scalability issue with large # of VFs - correctly return error on command failure on octeon fixes a corruption if any commands fail - fix modpost warning when building virtio_dma_buf harmless, but the fix is trivial Signed-off-by: Michael S.
