Documentation/admin-guide/mm/transhuge.rst (originally in Documentation/vm/transhuge.txt)
states that TRANSPARENT_HUGEPAGE_MADVISE is the default option for THP config:
"
madvise
will enter direct reclaim like ``always`` but only for regions
that are have used madvise(MADV_HUGEPAGE). This is the default
behaviour.
"
This patch changes mm/Kconfig to reflect that fact, accordingly.
Besides keeping consistency between documentation and the code behavior,
other reasons to perform this minor adjustment are noted at:
