Subject: netfilter: nf_tables: fix scheduling-while-atomic splat
From: Florian Westphal <fw@xxxxxxxxx>
commit 2024439bd5ceb145eeeb428b2a59e9b905153ac3 upstream.
nf_tables_check_loops() can be called from rhashtable list
walk so cond_resched() cannot be used here.
Fixes: 81ea01066741 ("netfilter: nf_tables: add rescheduling points during loop detection walks")
