Hi,
Here is a patch series to fix some issues on the trace event and function filters.
The first patch fixes an issue that the event filter can not handle the string pointer with BTF attribute tag. This happens with CONFIG_DEBUG_INFO_BTF=y and PAHOLE_HAS_BTF_TAG=y.
The second patch fixes a selftest issue on the function glob filter. Since mutex_trylock() can be an inline function, it is not a good example for ftrace. This replaces it with mutex_unlock().
Thank you,
