Subject: [PATCH v2 15/24] mm/hugetlb: Drop __unmap_hugepage_range definition from hugetlb.h
Date: Tue, 27 Apr 2021 12:13:08 -0400	[thread overview]
Message-ID: <20210427161317.50682-16-peterx@redhat.com> (raw)
In-Reply-To: <20210427161317.50682-1-peterx@redhat.com>

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