Subject: [PATCH net 0/3] Fixes for tc-taprio software mode

While working on some new features for tc-taprio, I found some strange
behavior which looked like bugs. I was able to eventually trigger a NULL
pointer dereference. This patch set fixes 3 issues I saw. Detailed
explanation in patches.

Vladimir Oltean (3):
  net/sched: taprio: avoid disabling offload when it was never enabled
  net/sched: taprio: make qdisc_leaf() see the per-netdev-queue pfifo
    child qdiscs
  net/sched: taprio: dereference oper and admin sched under RCU in
    taprio_destroy
