Wiring this into the module support is obviously the right way to do it :) I'm really very surprised it's so little code, even given the amount of prep you needed. I guess the basic uprobes machinery already did what we want these days, after all Eugene's systemwide uprobes work. But all the tests are reassuring (very nice tests). > +/* Match defined functions in both regular and dynamic ELF symbol tables. */ If only we had symtabs that really stuck around in executables without doing -Wl,--export-symbol :( Solaris got this right...
