Hi, Here is v2 of a series of some fixes/cleanups for the test modules and boot time selftest of kprobe events. The previous version is here;
https://lore.kernel.org/all/171671825710.39694.6859036369216249956.stgit@devnote2/ In this version, I just update the description of the first patch to add what bad things happen when the modules are built in. I found a WARNING message with some boot time selftest configuration, which came from the combination of embedded kprobe generate API tests module and ftrace boot-time selftest. Since kprobe and synthetic event generation API test modules add new events and lock it. Thus dynamic event remove-all operation failes. This also causes all ftracetest failed because it tries to cleanup all dynamic events before running test cases. The main problem is that these modules should not be built-in. But I also think this WARNING message is useless (because there are warning messages already) and the cleanup code is redundant. This series fixes those issues.
