  "message": "net: ntb_netdev: Fix statistics races\n\nntb_netdev updates shared net_device stats from per-QP RX and TX\ncallbacks. Once multiple queues are enabled, concurrent updates can be\nlost.\n\nUse per-CPU tstats for packet and byte counters and DEV_STATS_INC() for\nless frequent drop and error counters. Callbacks can run synchronously\nin the xmit path or asynchronously from a tasklet or the memcpy kthread.\nPin TX updates against migration in the kthread path. Use the IRQ-safe\nu64_stats helpers because netpoll can invoke the synchronous path with\nIRQs disabled.\n\nLet the core manage tstats while keeping transport teardown after\nunregister_netdev(), outside RTNL. RCU lets unregister wait for TX\ncompletions already updating stats, while later completions only consume\nthe skb and skip accounting and queue wake.\n\nFixes: 24d9e73c7e00 (\"net: ntb_netdev: Support ethtool channels for multi-queue\")\nCc: stable@vger.kernel.org\nSuggested-by: Jakub Kicinski \u003ckuba@kernel.org\u003e\nSigned-off-by: Koichiro Den \u003cden@valinux.co.jp\u003e\nReviewed-by: Eric Dumazet \u003cedumazet@google.com\u003e\nLink: https://patch.msgid.link/20260830151617.3546585-1-den@valinux.co.jp\nSigned-off-by: Jakub Kicinski \u003ckuba@kernel.org\u003e\n",
