I get very confused by the /sys/kernel/mm/transparent_hugepage/defrag
versus enabled flags, and this may be a terrible, even more confusing,
idea: but I've been surprised and sad to see defrag with a "defer"
option, but poor enabled without one; and it has crossed my mind that
perhaps the peculiar "madvise+defer" syntax in defrag might rather be
handled by "madvise" in defrag with "defer" in enabled?  Or something
like that: 4 x 4 possibilities instead of 5 x 3.

Please be gentle with me,
Hugh
