Akinobu Mita bb4c19e030 block: null_blk: make fault-injection dynamically configurable per device ... The null_blk driver has multiple driver-specific fault injection mechanisms. Each fault injection configuration can only be specified by a module parameter and cannot be reconfigured without reloading the driver. Also, each configuration is common to all devices and is initialized every time a new device is added. This change adds the following subdirectories for each null_blk device. /sys/kernel/config/nullb/<disk>/timeout_inject /sys/kernel/config/nullb/<disk>/requeue_inject /sys/kernel/config/nullb/<disk>/init_hctx_fault_inject Each fault injection attribute can be dynamically set per device by a corresponding file in these directories.
