include/uapi/asm-generic/unistd.h

include/uapi/asm-generic/unistd.h contains the system call numbers, based on the layout of the x86-64 architecture, which embeds the pointer to the syscall in the table:

#define __NR_io_setup     0
#define __NR_io_destroy   1
#define __NR_io_submit    2
…
#define __NR_cachestat  451

The macro __NR_syscalls keeps the number of syscalls:

#define __NR_syscalls   452
