What's the proper way to add a vendor-specific syscall? The comments in kern/syscalls.master suggest that they should be put in the range from 151-180, but most of that range is actually occupied. Only five nosys slots are available. If I add syscalls to the end of the list, they'll likely collide with future standard syscalls. Should I just added ~100 nosys syscalls to the end of the list, and put my custom syscalls afterwards? Is there any penalty to lengthening the list? -Alan
