Yes, the data I have was extracted by a script from the kernel syscall
tables and uses the kernel function names as used to build the tables.

There are some differences in the naming scheme but I haven't noticed
anything major other than the numbering schemes and some "old"/"new"
prefix or suffix differences.

The problem with the userspace headers is that they are not always in
sync with the syscalls the kernel actually implements...
