Subject: [PATCH] madvise.2: MADV_FREE clarify swapless behavior
Date: Thu, 29 Nov 2018 19:10:48 +0100 [thread overview]
Message-ID: <20181129181048.11010-1-mhocko@kernel.org> (raw)
From: Michal Hocko <mhocko@suse.com>
Since 93e06c7a6453 ("mm: enable MADV_FREE for swapless system") we
handle MADV_FREE on a swapless system the same way as with the swap
available. Clarify that fact in the man page.
