I'm really trying hard to figure out what it is that you want me to do. I'm looking for that "don't use dentry outside of VFS" moment. I get we have in the call stack the offsets of the file and a magical hash value that represents that vma. What I don't get is what is user space suppose to match that magical hash value to? Do you want me to trace all mmaps and trigger an event for them that show the hash value and the path names? If that's the case, what do I do about the major use case of tracing an application after it has mapped all it's memory to files? What about wasted ring buffer space for recording every mmap when the majority of them will not be used. It could risk dropping events of the mmaps we care about. Again, I'm not arguing with you. I'm trying to figure out what you are suggesting. -- Steve
