I mean, instead of having: ":%pd" We could have: "+0(*:%pB:dentry:name):string" Where the parsing could use BTF to see that this is a pointer to "struct dentry" and the member field is "name". This would also allow pretty much any other structure dereference. That is if BTF gives structure member offsets? -- Steve
