  SYSNO: 9, fork a new env which will be the child of the current env.
• sys_getenvid 🔒
  SYSNO: 2, get the EnvData::id or the pid. (a.k.a in Linux) of the current env.

  SYSNO: 8, cancel the map of the specified virtual address for the specified env.
• sys_panic 🔒
  SYSNO: 12, trigger the kernel’s panic with the given C-Style string.
