I don't mean to be rude but I doubt the utility of this whole plan. dump/restore are done on disk devices which are at least an order of magnitude slower than a syscall boundary crossing. Going from 4 syscalls to 1 can't make a bit of difference in restore(8) performance. So why is this faster? Something is likely slowing namei() down. However, this should be fixed by improving namei() or whichever subsystem is slowing restore down. Adding new syscalls is not the right answer. -Nate To Unsubscribe: send mail to [EMAIL PROTECTED] with "unsubscribe freebsd-hackers" in the body of the message
