[PATCH 0/2] block: null_blk: make fault-injection configurable via configfs

[Akinobu Mita]

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.
