Subject: [PATCH 5.10 30/42] mm: Remove examples from enum zone_type comment
Date: Mon,  8 Mar 2021 13:30:56 +0100	[thread overview]
Message-ID: <20210308122719.604428347@linuxfoundation.org> (raw)
In-Reply-To: <20210308122718.120213856@linuxfoundation.org>

From: Nicolas Saenz Julienne <nsaenzjulienne@suse.de>

commit 04435217f96869ac3a8f055ff68c5237a60bcd7e upstream

We can't really list every setup in common code. On top of that they are
unlikely to stay true for long as things change in the arch trees
independently of this comment.
