Subject: [PATCH] selftests: ftrace: Allow some tests to be run in a tracing
 instance

An tracing instance has several of the same capabilities as the top level
instance, but may be implemented slightly different. Instead of just writing
tests that duplicat the same test cases of the top level instance, allow a
test to be written for both the top level as well as for an instance.

If a test case can be run in both the top level as well as in an tracing
instance directory, then it should add a tag "# flags: instance" in the
header of the test file. Then after all tests have run, any test that has an
instance flag set, will run again within a tracing instance.

Oops, this needs '&> /dev/null' at the end to suppress its result.

Ah, I see. This is important. And I would rather like to show
it on the description line of each test so that we can check
which test log is run in an instance. E.g. passing "(instance)"
message to run_test() and testcase() as the 2nd arg, and print
it in testlog and console?

Thank you,

The -q should keep grep from outputting anything. It does on my end. Do
you see something different?

OK, I'll update to v4.

Ah, sorry I missed -q option... OK, it is good!
