Great description / justification. Increasing delays always stinks, but sometimes is unavoidable. > Signed-off-by: dioyc_zhang <[email protected]> Any chance you could improve the "Name" part of your Signed-off-by (and patch authorship, too)? Is "dioyc_zhang" really a name that you usually use to identify yourself? It seems like it was just git automatically assigning something since you typed in an email address but not a name... -Doug
