Subject: [PATCH v2 net 0/2] netfilter: updates for net

v2: in patch 1, prefer volatile to stdatomic.h. No other changes.

The following patchset contains Netfilter fixes for *net*:

1) Fix a silly bug in conntrack selftest, busyloop may get optimized to
   for (;;), reported by Yi Chen.

2) Introduce new NFTA_DEVICE_PREFIX attribute in nftables netlink api,
   re-using old NFTA_DEVICE_NAME led to confusion with different
   kernel/userspace versions.  This refines the wildcard interface
   support added in 6.16 release.  From Phil Sutter.
