20 * The sysmsg holds the kernelland version of a system call.
21 * It typically preceeds the usrmsg and syscall arguments in sysunion
22 * (see sys/sysunion.h)
37 * The usrmsg holds the userland version of the system call message which
38 * typically preceeds the original user arguments. This message structure
39 * is typically loaded by the copyin() and adjusted prior to copyout(), but
40 * not used in the nominal running of the system call.
