From bafac2a512bf4fd2ce7520f3976ce8aab4435f74 Mon Sep 17 00:00:00 2001 From: Patrick McHardy Date: Mon, 27 Feb 2006 13:04:17 -0800 Subject: [NETFILTER]: Restore {ipt,ip6t,ebt}_LOG compatibility The nfnetlink_log infrastructure changes broke compatiblity of the LOG targets. They currently use whatever log backend was registered first, which means that if ipt_ULOG was loaded first, no messages will be printed to the ring buffer anymore. Restore compatiblity by using the old log functions by default and only use the nf_log backend if the user explicitly said so. Signed-off-by: Patrick McHardy Signed-off-by: David S.

(akpm: I expect that mm_struct.task_size will become the way in which we finally sort out the confusion between 32-bit processes and 32-bit mm's. It may need tweaks, but at this stage this patch is powerpc-only.)
