block: null_blk: make fault-injection dynamically configurable per deviceThe null_blk driver has multiple driver-specific fault injectionmechanisms. Each fault injection configuration can only be specified by amodule parameter and cannot be reconfigured without reloading the driver.Also, each configuration is common to all devices and is initialized everytime a new device is added.This change adds the following subdirectories for each null_blk device./sys/kernel/config/nullb//timeout_inject/sys/kernel/config/nullb//requeue_inject/sys/kernel/config/nullb//init_hctx_fault_injectEach fault injection attribute can be dynamically set per device by acorresponding file in these directories.Signed-off-by: Akinobu Mita Link: https://lore.kernel.org/r/20230327143733.14599-3-akinobu.mita@gmail.comSigned-off-by: Jens Axboe List of files: /linux-6.15/drivers/block/null_blk/Kconfig
