Christoph Hellwig bfd8947194 nvme: fixes for NVME_IOCTL_IO_CMD on the char device ... Make sure we synchronize access to the namespaces list and grab a reference to the namespace before doing I/O. Make sure to reject the ioctl if multiple namespaces are present as it's entirely unsafe, and warn when using it even with a single namespace.
