When a process change it's name via "prctl" system call, it can't be profiled with oprofile at all.

"opreport" is failed to load JIT dump file in session directory when "--root" option is given and the "root directory" doesn't contain the session directory or the JIT dump file(That means "root directory" and "session directory" is totally separated.)

If '--root' is missed or given root directory contains session directory or JIT dump file, it works fine.

Oprofile offers opagent library to support JIT support.
If a JIT agent is made with the library it produces .dump file to store compiled object by JIT compiler. When operf is done with profiling opjitconv component detect dump files and store them with ".jo" extension into session directory which is given to operf.
