Similar to other handle_aiocb_* functions, handle_aiocb_ioctl needs to cater for the possibility that ioctl is interrupted by a signal. Otherwise, the I/O is incorrectly reported as a failure to the guest. Reported-by: Gordon Watson <gwatson@redhat.com> Signed-off-by: Paolo Bonzini <pbonzini@redhat.com>
