Hi, thank you for reporting this. IRC oftc.net #systemtap may also be a good venue if you're interested in partial answers quickly over full answers at an unknown time. Unfortunately since the kernel may change the same tapsets can yield different results until they're fixed to match the newer kernel too. They are generally coded to use multiple fallbacks, so if only part of the information is in the same place the d_name() function would yield just the name instead of "". In this case the last commit to tapsets/linux/dentry.stp was in 2020 so it looks like we may have some catching up to the kernel to do. I'll investigate more (i.e. delve into kernel git history) and get back to you.
