From 169384fbe8513185499bcbb817d198e6a63eb37e Mon Sep 17 00:00:00 2001 From: Florian Westphal Date: Wed, 21 Jun 2023 10:36:26 +0200 Subject: netfilter: nf_tables: allow loop termination for pending fatal signal abort early so task can exit faster if a fatal signal is pending, no need to continue validation in that case.
