NOTES

20       Note that ftime(3), profil(3), and ulimit(3) are implemented as library
21       functions.
22
23       Some system calls,  like  alloc_hugepages(2),  free_hugepages(2),  iop‐
24       erm(2), iopl(2), and vm86(2) exist only on certain architectures.
25
26       Some  system  calls, like ipc(2), create_module(2), init_module(2), and
27       delete_module(2) exist only when the Linux kernel was built  with  sup‐
28       port for them.
