Subject: [for-next][PATCH 23/23] selftests/kprobe: Do not test for GRP/ without event failures
From: "Steven Rostedt (Google)" <rostedt@...dmis.org>
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.
