From bfb85c9f753a7172bd962e8717118191dfd612cc Mon Sep 17 00:00:00 2001 From: Randy Dunlap Date: Sun, 21 Oct 2007 16:24:27 -0700 Subject: [PATCH] [ATM]: Fix clip module reload crash. net/atm/clip.c crashes the kernel if it (module) is loaded, removed, and then loaded again. Its exit call to neigh_table_clear() should destroy the cache after freeing it. Signed-off-by: Randy Dunlap Signed-off-by: David S.
