I found it convenient to have everything in sysfs as everything is visible
from the shell without needing any extra tooling. And I did that because I
thought ioctls should not be added... We could add one though, but then I
do not see much value since cdl-tools (cdladm utility) and sg3utils/sdparm
can give that information already.
