Two net_sched fixes for stable
Hi, David Can you queue the following commits for stable? They fix a sleep-in-atomic warning reported by Roland. commit efbf78973978b0d25af59bc26c8013a942af6e64 Author: Cong Wang Date: Mon Dec 4 10:48:18 2017 -0800 net_sched: get rid of rcu_barrier() in tcf_block_put_ext() commit df45bf84e4f5a48f23d4b1a07d21d566e8b587b2 Author: Jiri Pirko Date: Fri Dec 8 19:27:27 2017 +0100 net: sched: fix use-after-free in tcf_block_put_ext This problem was introduced by: commit e2ef75445340ca7ec2c4558f84ae6c8c5d650fc8 Author: Cong Wang Date: Mon Sep 11 16:33:31 2017 -0700 net_sched: fix reference counting of tc filter chain so should apply to 4.14 too. For 4.15, they can just apply nearly cleanly. However, it is not straight-forward to cherry pick them to 4.14 due to some big changes between 4.14 and 4.15. Please let me know how you want to handle this for 4.14. Thanks.
