Subject: [PATCH AUTOSEL 4.19 33/34] xen/balloon: fix ballooned page accounting without hotplug enabled
Date: Fri, 20 Dec 2019 09:34:32 -0500 [thread overview]
Message-ID: <20191220143433.9922-33-sashal@kernel.org> (raw)
In-Reply-To: <20191220143433.9922-1-sashal@kernel.org>
From: Juergen Gross <jgross@suse.com>
[ Upstream commit c673ec61ade89bf2f417960f986bc25671762efb ]
When CONFIG_XEN_BALLOON_MEMORY_HOTPLUG is not defined
reserve_additional_memory() will set balloon_stats.target_pages to a
wrong value in case there are still some ballooned pages allocated via
alloc_xenballooned_pages().
This will result in balloon_process() no longer be triggered when
ballooned pages are freed in batches.
