====================
Netfilter fixes for net

The following patch contains Netfilter fixes for your net tree, they are:

1) nf_log_unregister() should only set to NULL the logger that is being
   unregistered, instead of everything else. Patch from Florian Westphal.

2) Fix a crash when accessing physoutdev from PREROUTING in br_netfilter.
   This is partially reverting the patch to shrink nf_bridge_info to 32 bytes.
   Also from Florian.

3) Use existing match/target extensions in the internal nft_compat extension
   lists when the extension is family unspecific (ie. NFPROTO_UNSPEC).

4) Wait for rcu grace period before leaving nf_log_unregister().
