====================
Netfilter updates for net-next

The following series contains Netfilter updates for net-next:

1) Make legacy xtables configs user selectable, from Breno Leitao.

2) Fix a few sparse warnings related to percpu, from Uros Bizjak.

3) Use strscpy_pad, from Justin Stitt.

4) Use nft_trans_elem_alloc() in catchall flush, from Florian Westphal.

5) A series of 7 patches to fix false positive with CONFIG_RCU_LIST=y.
   Florian also sees possible issue with 10 while module load/removal
   when requesting an expression that is available via module. As for
   patch 11, object is being updated so reference on the module already
   exists so I don't see any real issue.

   Florian says:

   "Unfortunately there are many more errors, and not all are false positives.

   First patches pass lockdep_commit_lock_is_held() to the rcu list traversal
   macro so that those splats are avoided.

   The last two patches are real code change as opposed to
   'pass the transaction mutex to relax rcu check':

   Those two lists are not protected by transaction mutex so could be altered
   in parallel.

   This targets nf-next because these are long-standing issues."
