| H A D | Kconfig | bb4c19e0 Mon Mar 27 14:37:33 GMT 2023 Akinobu Mita <[email protected]> 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.
