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].
