Re: [PATCH net v3 0/9] net/sched: clamp quantum/psched_mtu in change paths

Hello:

This series was applied to netdev/net.git (main)

This is a followup to commit 709f34f7c28d ("net/sched: fq: add overflow
bounds to quantum and initial quantum").

The quantum_backlog_overflow series and the five siblings that followed
clamped the init-path quantum in fq, fq_codel, fq_pie, hhf, sfq. The
change() paths were not clamped but it is the same pattern, same writer
of q->quantum, same privilege level (CAP_NET_ADMIN in a user namespace).
A user can override the init clamp via tc qdisc change, restoring the
small-quantum deficit spin that the init clamp was meant to prevent.
