Subject: [PATCH v10 1/8] mm: ksm: Export ksm_madvise()
Date: Mon, 4 Nov 2019 09:47:53 +0530 [thread overview]
Message-ID: <20191104041800.24527-2-bharata@linux.ibm.com> (raw)
In-Reply-To: <20191104041800.24527-1-bharata@linux.ibm.com>
KVM PPC module needs ksm_madvise() for supporting secure guests.
Guest pages that become secure are represented as device private
pages in the host. Such pages shouldn't participate in KSM merging.
