Subject: [PATCH v2 net-next 0/4] net/sched: tc_dump_qdisc() optimizations
Date: Tue, 28 Apr 2026 17:04:10 +0000 [thread overview]
Message-ID: <20260428170414.250566-1-edumazet@google.com> (raw)
Before converting tc_dump_qdisc() to RCU, we make the following changes:
- Use for_each_netdev_dump() instead of for_each_netdev()
- Only dump qdiscs of a single device at user space request.
v2: addressed Jakub feedback (thanks!)
Eric Dumazet (4):
net/sched: propagate tc_fill_tclass() error
net/sched: tc_dump_qdisc_root() refactor
net/sched: switch tc_dump_qdisc() to for_each_netdev_dump()
net/sched: speedup tc_dump_qdisc() when tcm_ifindex is provided
