I tried this approach but am having trouble getting a patch to compile with both older glibc and recent glibc. With older glibc I will get a "no previous prototype" compilation error. I can fix this error by adding a prototype but this results in a "redundant redeclaration" error with newer glibc. -- To unsubscribe from this list: send the line "unsubscribe linux-perf-users" in the body of a message to [email protected] More majordomo info at http://vger.kernel.org/majordomo-info.html
