Subject: [PATCH v2-updated 2/2] m/hugetlb: Rename ARCH_WANT_HUGETLB_PAGE_OPTIMIZE_VMEMMAP
Date: Tue, 11 Apr 2023 19:52:14 +0530	[thread overview]
Message-ID: <20230411142214.64464-2-aneesh.kumar@linux.ibm.com> (raw)
In-Reply-To: <20230411142214.64464-1-aneesh.kumar@linux.ibm.com>

Now we use ARCH_WANT_HUGETLB_PAGE_OPTIMIZE_VMEMMAP config option
to indicate devdax and hugetlb vmemmap optimization support. Hence
rename that to a generic ARCH_WANT_OPTIMIZE_VMEMMAP
