When I execute "insmod nvme.ko use_threaded_interrupts=1", I find it difficult to determine whether it is successful or not, So I want to add read-only parameter to '/sys/module/nvme/parameters/use_threaded_interrupts', When insmoded successfully. # cat /sys/module/nvme/parameters/use_threaded_interrupts # 1
