Subject: [request for stable inclusion] mm/memory-failure.c: fix memory leak in successful soft offlining
Date: Thu, 13 Feb 2014 09:41:58 +0800	[thread overview]
Message-ID: <52FC22E6.9010300@huawei.com> (raw)

Hi Naoya or Greg,

f15bdfa802bfa5eb6b4b5a241b97ec9fa1204a35
mm/memory-failure.c: fix memory leak in successful soft offlining

This patche look applicable to stable-3.10.
After a successful page migration by soft offlining, the source 
page is not properly freed and it's never reusable even if we 
unpoison it afterward. This is caused by the race between freeing 
page and setting PG_hwpoison.
It was built successful for me. What do you think?

Thanks,
Xishi Qiu
