Sorry about the missing background. You may check
[0] http://lkml.indiana.edu/hypermail/linux/kernel/1211.0/03025.html
http://patchwork.ozlabs.org/patch/193414/
http://patchwork.ozlabs.org/patch/202385/
And as it is very similar to that of commit 12660b17, so I think it's
not needed to repeat that in the change log.
Thanks, Zhong
