Re: [PATCH net-next v3 1/6] net: sched: introduce qdisc-specific drop reason tracing

On 2/6/26 5:24 PM, Jesper Dangaard Brouer wrote:

Create new enum qdisc_drop_reason and trace_qdisc_drop tracepoint
for qdisc layer drop diagnostics with direct qdisc context visibility.

The new tracepoint includes qdisc handle, parent, kind (name), and
device information. Existing SKB_DROP_REASON_QDISC_DROP is retained
for backwards compatibility via kfree_skb_reason().

Convert FQ, FQ_CoDel, CoDel, SFB, and pfifo_fast to use the new
infrastructure.

I think it would be useful to add dropreason-qdisc.h to the net/sched
maintainer's entry.
