First off, for each open file, does the kernel keep a unique vnode structure? If so, will it have at most one vm_object reference at any time? I am guessing that mmaping a file will create vm_object with a vnode pager that references vnode. But then under what circumstances does vnode not have a valid vm_object?
Well ... also ahh what is the difference between VMIO and non-VMIO? Does the latter just mean that phyio? You can smack my head if these questions are so dumb. John To Unsubscribe: send mail to [EMAIL PROTECTED] with "unsubscribe freebsd-hackers" in the body of the message
