missing sytemtap kernel.trace("net*") on newer Fedora kernels

[William Cohen]

I was looking at the perf netdev-times script:

http://git.kernel.org/cgit/linux/kernel/git/torvalds/linux.git/tree/tools/perf/scripts/python/bin/netdev-times-record

Which uses the following perf tracepoints:

#!/bin/bash
perf record -e net:net_dev_xmit -e net:net_dev_queue		\
		-e net:netif_receive_skb -e net:netif_rx		\
		-e skb:consume_skb -e skb:kfree_skb			\
		-e skb:skb_copy_datagram_iovec -e napi:napi_poll	\
		-e irq:irq_handler_entry -e irq:irq_handler_exit	\
		-e irq:softirq_entry -e irq:softirq_exit		\
		-e irq:softirq_raise $@


On the rhel7 kernel all of the tracepoints are available,  However, on Fedora 20 none of the kernel.trace("net*"), kernel.trace("*skb*"), or kernel.trace("napi_poll") tracepoints are there.

Has anyone else noticed the missing tracepoints on Fedora 20?
