Hi


I just upgraded some testing host to 4.15.0-rc2+ kernel

And after some time of traffic processing - when traffic on all ports
reach about 3Mpps - memleak started.

Some observations - when i disable tso on all cards there is more
memleak.

When traffic starts to drop - there is less and less memleak
below link to memory usage graph:

And there is rising slab_unrecl - Amount of unreclaimable memory used
for slab kernel allocations


Forgot to add that im using hfsc and qdiscs like pfifo on classes.

Maybe some error case I missed in the qdisc patches I'm looking into
it.

Thanks,
John
