This system call table was found in the Linux kernel source code of Ubuntu22.04.1-Desktop-LTS when I was learning the Linux kernel . I personally feel that it is very useful when learning about Linux kernel system calls, so I share it with readers. It should be emphasized that the Linux kernel version corresponding to this system call table is 5.19.0-50-generic , and this version of the Linux kernel contains a total of 360 system calls. In addition, there may be some differences in other versions of the Linux kernel (some system calls may have been abandoned, or some system call numbers may change), please readers to distinguish by themselves.
