charset=UTF-8 Content-Transfer-Encoding: 8bit Hi Jason, Thanks for the review. This was a timing race, not intentional: your v3 reply (the Reviewed-by plus the else-branch nit) arrived at 10:30, while v4 was sent at 10:32 and had already been prepared without it. I should have checked the thread before sending. I'll send a v5 as a new thread with the unnecessary else removed, exactly as you suggested, and your Reviewed-by carried on patch 1. Patch 2 is unchanged. Thanks, Rongzheng
