From: Lai Jiangshan <laijs@linux.alibaba.com>

The first two patches fix two old possible bugs.
And the others are just cleanups.

Changed from [V1]:
	The two fixes are changed as Sean suggested.
	And it triggers a different cleanup as patch3-6.
	Patch 7(V1's patch 3) is also updated as Sean suggested.
	Patch 8-10 which are not related to the fixes are unchanged.
	V1's patch 7 is dropped.
