Subject: [PATCH V1 04/11] powerpc/mm: Rename pte fragment functions
Date: Mon, 16 Apr 2018 16:57:17 +0530 [thread overview]
Message-ID: <20180416112724.9677-6-aneesh.kumar@linux.ibm.com> (raw)
In-Reply-To: <20180416112724.9677-1-aneesh.kumar@linux.ibm.com>
From: "Aneesh Kumar K.V" <aneesh.kumar@linux.vnet.ibm.com>
We rename the alloc and get_from_cache to indicate they operate on pte
fragments. In later patch we will add pmd fragment support.
No functional change in this patch.
