Rusty, here is just patch 1 (using bool as return value in notify API). Thanks. Heinz Graalfs (9): virtio_ring: change host notification API virtio_ring: let virtqueue_{kick()/notify()} return a bool virtio_net: verify if virtqueue_kick() succeeded virtio_test: verify if virtqueue_kick() succeeded virtio_ring: add new function virtqueue_is_broken() virtio_blk: verify if queue is broken after virtqueue_get_buf() virtio_console: verify if queue is broken a...

...queues. Here are the details of the error. A hang (loop) occurs when a machine check is handled on System z due to a vlan device removal. A loop spinning for a response for final IO in virtnet_send_command() will never complete successfully because of a previous unsuccessfull host kick operation (virtqueue_kick()). Patch [1] changes the guest->host notification API. A potential error returned by the host during notify() should not be ignored, but used in order to reflect the error back to the affected virtqueue. Patch [2] changes virtqueue_kick() and virtqueue_notify() to return a bool depending...

Recent changes to drivers/virtio broke compilation for the tests in tools/virtio. The following patches are build fixes for those changes, as well as a fix for a typo that would have never built. The changes were tested on my amd64 system against 3.14-rc2. Joel Stanley (3): tools/virtio: update internal copies of headers tools/virtio: fix missing kmemleak_ignore symbol tools/virtio: add a

...re likely stuck with it now, so this layer just adds complexity and overhead. Further, the need to pass vq twice to each call (as in dev->vq->vq_ops->kick(dev->vq) ) adds potential for cut and paste errors. This patchset does the following: - add inline wrappers converting the above to virtqueue_kick(dev->vq) - convert all users to this API - remove vq_ops indirection, implementing virtqueue_xx directly in virtio_ring Note that if we ever want to add another vring implementation, we'll only need to revert the last patch in the series, devices won't have to change. -- MST M...
