Bruce Fields" [ Upstream commit 5b7b15aee641904ae269be9846610a3950cbd64c ] We're encoding a single op in the reply but leaving the number of ops zero, so the reply makes no sense. Somewhat academic as this isn't a case any real client will hit, though in theory perhaps that could change in a future protocol extension. Reviewed-by: Jeff Layton Signed-off-by: J.
