Dmitry Osipenko b9ad22d24e virtio/vdrm: Fix lockup in vdrm_host_sync() ... The vdrm_execbuf() missed to set the seqno field for requests sent to host. This causes vdrm_host_sync() to lock up due to the unset seqno in a case where two or more threads are using vdrm_execbuf() and vdrm_send_req() concurrently, like in this scenario: thread1: vdrm_send_req() shmem->seqno=1 req->seqno=2 thread2: vdrm_execbuf() shmem->seqno=1 req->seqno=0 thread1: vdrm_host_sync() shmem->seqno=0 req->seqno=2 Fix the lockup by setting the seqno in vdrm_execbuf().
