Subject: [PATCH 22/28] mm: remove both instances of __vmalloc_node_flags
Date:   Wed,  8 Apr 2020 13:59:20 +0200
Message-Id: <20200408115926.1467567-23-hch@lst.de>
In-Reply-To: <20200408115926.1467567-1-hch@lst.de>
References: <20200408115926.1467567-1-hch@lst.de>
MIME-Version: 1.0
Content-Transfer-Encoding: 8bit
Sender: linux-kernel-owner@vger.kernel.org
Precedence: bulk

The real version just had a few callers that can open code it and
remove one layer of indirection.  The nommu stub was public but only
had a single caller, so remove it and avoid a CONFIG_MMU ifdef in
vmalloc.h.
