Subject: [PATCH] mm: kconfig: make Transparent Hugepage Support sysfs defaults to match the documentation
Date: Mon, 18 Nov 2019 22:01:02 -0500 [thread overview]
Message-ID: <20191119030102.27559-1-aquini@redhat.com> (raw)
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:
https://bugzilla.redhat.com/show_bug.cgi?id=1772133
