5.10.y backported the commit
09bcf9254838 ("selftests/ftrace: Add new test case which checks non unique symbol")
which added a new test case to check non-unique symbol. However, 5.10.y
didn't backport the kernel commit
b022f0c7e404 ("tracing/kprobes: Return EADDRNOTAVAIL when func matches several symbols")to support the functionality from kernel side. Backport it in this patch series.
The first two patches are presiquisites. The 4th commit is a fix commit
for the 3rd one.
Build and test case passed.
