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
