Hi Chao,
Thanks for v4. The new commit message paragraph describes the lock change
accurately. I compared v4 with v3: the code in 0001 and the test
in 0002 are unchanged. I cross checked the v4 and its results look same as
v3.
I think the patch is ready for a committer, and I've marked the CF entry
Ready for Committer.
