From 4fe683f50d3fc8e36d4749277631dfc711393aa0 Mon Sep 17 00:00:00 2001 From: Thomas Graf Date: Wed, 5 Jul 2006 20:47:28 -0700 Subject: [PKT_SCHED]: Fix error handling while dumping actions "return -err" and blindly inheriting the error code in the netlink failure exception handler causes errors codes to be returned as positive value therefore making them being ignored by the caller. May lead to sending out incomplete netlink messages. Signed-off-by: Thomas Graf Signed-off-by: David S.
