Thanks for the tip!
See reason:https://github.com/iovisor/bcc/issues/3533

This link only explains why TCP needs it, my question is why not
do it for other protocols too, therefore neither this link nor you
answers it.

BTW, net/core/drop_monitor.c is based on kfree_skb() tracepoint
too, in case you are only interested in tracepoints not other things.

Thanks.
