Actions are fine because they are intended to be globaly shared.
[i.e A classifier on ethx with qdiscA:Y (in/egress) can share an action
with classifer on ethy with qdiscB:Z (eg/ingress)].
Yes, in that case its not a problem. The case where it behaves
differently than now is when only a single reference exists.
Like you i need to digest the patches to understand the impact on the
rest but one thing i did notice was the last patch (replacement of
pfifo_fast):
prioritization based on TOS/DSCP (setsockopt) would no longer work, some
user space code may suffer (routing daemons likely). One suggestion to
fix it is to load pfifo qdisc (which does what fifo_fast is attempting)
for drivers that are h/ware multiq capable.
That would perform priorization within each qdisc, the individual
qdiscs would still be transmitted using seperate HW queues though.
