2.6.27-stable review patch. If anyone has any objections, please let us know. ------------------ From: Herbert Xu [ Upstream commit: 7891cc818967e186be68caac32d84bfd0a3f0bd2 ] When a fib6 table dump is prematurely ended, we won't unlink its walker from the list. This causes all sorts of grief for other users of the list later. Reported-by: Chris Caputo Signed-off-by: Herbert Xu Signed-off-by: David S.
