The attached patch adds stubs for Linux 2.6.17 syscalls. Even though
some syscalls were not in official 2.6.16 kernel (e.g.,
[gs]et_robust_list() showed up in 2.6.17-rc1), GNU libc started using
them for NPTL and FC4 updated 2.6 kernel to 2.6.17 later.
If you have any concern or objection, please speak up now.
Thanks,
Jung-uk Kim
