Linux: Add getdents64 system call
No 32-bit system call wrapper is added because the interface is problematic because it cannot deal with 64-bit inode numbers and 64-bit directory hashes. A future commit will deprecate the undocumented getdirentries and getdirentries64 functions. Reviewed-by: Carlos O'Donell <carlos@redhat.com>
