Subject: Re: khugepaged doesn't want to freeze
Date: Tue, 8 Nov 2011 16:29:10 +0100 [thread overview]
Message-ID: <1320766151-2619-1-git-send-email-aarcange@redhat.com> (raw)

[PATCH] thp: reduce khugepaged freezing latency
Beware patch untested but I suspect the problem was the lack of
wakeup during long schedule_timeout. And a missing try_to_freeze in
case alloc_hugepage repeatedly fails in the CONFIG_NUMA=n case.
