It is not just readlink that we would need. We would require

sys_handle_readlink, sys_handle_stat64, sys_handle_link, sys_handle_chown,
sys_handle_setxattr, sys_handle_getxattr, sys_handle_listxattr,
sys_handle_removexattr, sys_handle_utimes, compat_sys_handle_utimes

I have most of the changes done, so if we are ok adding all these
new syscalls i can post the patch series.
