From 5648b203ebfce5b9b26bc4a95d4072f30d8f8f66 Mon Sep 17 00:00:00 2001 From: David Miller Date: Sun, 13 Feb 2011 16:37:07 -0800 Subject: [PATCH] klist: Fix object alignment on 64-bit. commit 795abaf1e4e188c4171e3cd3dbb11a9fcacaf505 upstream. Commit c0e69a5bbc6f ("klist.c: bit 0 in pointer can't be used as flag") intended to make sure that all klist objects were at least pointer size aligned, but used the constant "4" which only works on 32-bit. Use "sizeof(void *)" which is correct in all cases. Signed-off-by: David S.
