Subject: [RFC][PATCH 0/3] pagemap handles transparent hugepage
Date: Mon, 19 Dec 2011 13:38:36 -0500 [thread overview]
Message-ID: <1324319919-31720-1-git-send-email-n-horiguchi@ah.jp.nec.com> (raw)
Transparent hugepage (thp) splits itself when kernel cannot work on it
in hugepage unit. Thp split can reduce performance merit of thp, so we
are now making efforts to handle thp as it is if possible.
As one of such efforts, I suggest to make pagemap aware of thp.
Could you review and comment on them?
Thanks,
Naoya
