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. Regards, Surya Poondla
