This includes some patches to fix 2 issues on ftrace selftests.
- eprobe filter and eprobe syntax test case were introduced but it
doesn't check whether the kernel supports eprobe filter. Thus the
new test case fails on the kernel which has eprobe but not support
eprobe filter. To solve this issue, add a filter description to
README file [1/3] and run the filter syntax error test only if the
description is found in the README file [2/3].
- Recently objtool adds prefix symbols for the function padding nops,
and the probepoint test case fails because this probepoint test case
tests whether the kprobe event can probe the target function and the
functions next to the target function. But the prefix symbols can not
be probed. Thus these prefix symbols must be skipped [3/3].
Thank you,
