Try to check fs/binfmt_elf.c, especially the load_elf_binary() function. Also, remember that file blocks are read on-demand, that means if they are not needed, then it won't be loaded to RAM. So, even if your binary has debug symbols, it won't occupy RAM unless they are read (e.g when gdb need to correlate address with symbols) -- regards, Mulyadi Santosa Freelance Linux trainer blog: the-hydra.blogspot.com -- To unsubscribe from this list: send an email with "unsubscribe kernelnewbies" to [email protected] Please read the FAQ at http://kernelnewbies.org/FAQ
