Subject: [RFC PATCH 4/4] mm: madvise allow remove operation for hugetlbfs
Date: Thu, 16 Apr 2015 16:02:58 -0700 [thread overview]
Message-ID: <1429225378-22965-5-git-send-email-mike.kravetz@oracle.com> (raw)
In-Reply-To: <1429225378-22965-1-git-send-email-mike.kravetz@oracle.com>
Now that we have hole punching support for hugetlbfs, we can
also support the MADV_REMOVE interface to it.
