From 56db1c5f41c2ed0300ca570fea279a7c189c18fb Mon Sep 17 00:00:00 2001 From: Jean Sacren Date: Sun, 3 Feb 2013 21:34:10 +0000 Subject: mcast: do not check 'rv' twice in a row With the loop, don't check 'rv' twice in a row. Without the loop, 'rv' doesn't even need to be checked. Make the comment more grammar-friendly. Signed-off-by: Jean Sacren Signed-off-by: David S.
