Subject: [PATCH 19/25] mm: remove hmm_vma_alloc_locked_page
Date: Mon, 17 Jun 2019 14:27:27 +0200 [thread overview]
Message-ID: <20190617122733.22432-20-hch@lst.de> (raw)
In-Reply-To: <20190617122733.22432-1-hch-jcswGhMUV9g@public.gmane.org>
The only user of it has just been removed, and there wasn't really any need
to wrap a basic memory allocator to start with.
