[ Upstream commit f5eab65ff2b76449286d18efc7fee3e0b72f7d9b ]

A new feature is added where kprobes (and other probes) do not need to explicitly state the event name when creating a probe. The event name will come from what is being attached.

That is:

# echo 'p:foo/ vfs_read' > kprobe_events

Will no longer error, but instead create an event:

# cat kprobe_events p:foo/p_vfs_read_0 vfs_read

This should not be tested as an error case anymore. Remove it from the selftest as now this feature "breaks" the selftest as it no longer fails as expected.
