From b0270550229b3efeadfcac1cf04415dfea27915e Mon Sep 17 00:00:00 2001 From: Eric Dumazet Date: Mon, 22 Apr 2019 18:35:01 -0700 Subject: ipv6: fib6_info_destroy_rcu() cleanup We do not need to clear f6i->rt6i_exception_bucket right before freeing f6i. Note that f6i->rt6i_exception_bucket is properly protected by f6i->exception_bucket_flushed being set to one in rt6_flush_exceptions() under the protection of rt6_exception_lock.
