5.4-stable review patch. If anyone has any objections, please let me know.

commit 5ba8b837b522d7051ef81bacf3d95383ff8edce5 upstream.
htb_qlen_notify() always deactivates the HTB class and in fact could trigger a warning if it is already deactivated. Therefore, it is not idempotent and not friendly to its callers, like fq_codel_dequeue().
Any reason why the entire patch series wasn't backported?

Only one file in the patch series isn't present:
$ ls net/sched/sch_{codel,drr,ets,fq_codel,hfsc,htb,qfq}.c > /dev/null ls: cannot access 'net/sched/sch_ets.c': No such file or directory
This commit is a part of a larger fix so it alone doesn't make sense.
There is a CVE identifier for this commit, but it's a partial fix for the overall issue.
Thanks, Siddh
