This patch set makes null_blk driver-specific fault-injection dynamically
configurable per device via configfs.
Since the null_blk driver supports configuration such as device creation
via configfs, it is natural to configure fault-injection via configfs as
well.
Currently, only the debugfs interface is provided for dynamically
configuring fault-injection, so this introduces a compatible interface via
configfs.
