The unwind info for the Linux kernel does get included in the core-dump (see Roland McGrath's work on this), but it is not available via /proc. Note that in the future, it won't be necessary to do a syscall. Instead, the kernel's unwind info will be available (to the running process) via dl_iterate_phdr(). I'm not sure though how this is supposed to be made accessible to programs such as gdb. --david
