Hi Linus,

Probes fixes for v6.6-rc6.2:

- kprobe-events: Fix kprobe events to reject if the attached symbol
is not unique name because it may not the function which the user
want to attach to. (User can attach a probe to such symbol using
the nearest unique symbol + offset.)

- selftest: Add a testcase to ensure the kprobe event rejects non
unique symbol correctly.
