Hi, These are RFC patches for adding a notification queue to allow sending notifications from host to guest. It also adds support for blocking remote posix locks using the newly introduced notification queue. These patches apply on top of 5.4-rc8 plus following patch series I had posted a while back. https://lkml.org/lkml/2019/10/30/493 These changes require virtio spec changes as well. I have yet to do that. Thanks Vivek Vivek Goyal (4): virtiofs: Provide a helper function for virtqueue initialization virtiofs: Add an index to keep track of first request queue virtiofs: Add a virtqueue for notifications virtiofs: Support blocking posix locks (fcntl(F_SETLKW)) fs/fuse/virtio_fs.c | 328 ++++++++++++++++++++++++++++++--- include/uapi/linux/fuse.h | 7 + include/uapi/linux/virtio_fs.h | 5 + 3 files changed, 310 insertions(+), 30 deletions(-) -- 2.20.1
