VHOST_NEW_WORKER needs the device in vhost_task mode, so userspace has to issue VHOST_SET_FORK_FROM_OWNER with VHOST_FORK_OWNER_TASK before VHOST_SET_OWNER: our fork_from_owner_default is kthread. https://virtuozzo.atlassian.net/browse/VSTOR-107537 Feature: vhost-blk: in-kernel accelerator for virtio-blk guests Suggested-by: Pavel Tikhomirov Signed-off-by: Alexander Ivanov --- drivers/vhost/blk.c | 8 ++++++++ 1 file changed, 8 insertions(+) diff --git a/drivers/vhost/blk.c b/drivers/vhost/blk.c index b170439a1806..ab3b8c4c2d5a 100644 --- a/drivers/vhost/blk.c +++ b/drivers/vhost/blk.c @@ -909,6 +909,14 @@ static long vhost_blk_ioctl(struct file *f, unsigned int ioctl, return vhost_blk_set_features(blk, features); case VHOST_RESET_OWNER: return vhost_blk_reset_owner(blk); + case VHOST_NEW_WORKER: + case VHOST_FREE_WORKER: + case VHOST_ATTACH_VRING_WORKER: + case VHOST_GET_VRING_WORKER: + mutex_lock(&blk->dev.mutex); + ret = vhost_worker_ioctl(&blk->dev, ioctl, argp); + mutex_unlock(&blk->dev.mutex); + return ret; default: mutex_lock(&blk->dev.mutex); ret = vhost_dev_ioctl(&blk->dev, ioctl, argp); -- 2.53.0 _______________________________________________ Devel mailing list Devel@openvz.org https://lists.openvz.org/mailman/listinfo/devel
