Subject: [PATCH v5 15/26] mm/hugetlb: Drop __unmap_hugepage_range definition from hugetlb.h
Date: Thu, 15 Jul 2021 16:16:14 -0400	[thread overview]
Message-ID: <20210715201614.211661-1-peterx@redhat.com> (raw)
In-Reply-To: <20210715201422.211004-1-peterx@redhat.com>

Drop it in the header since it's only used in hugetlb.c.

Suggested-by: Mike Kravetz <mike.kravetz@oracle.com>
