Please keep in mind that, like no other data structure in the system, adding something to struct vm_page has serious memory use considerations. One longword extra would consume 1MB of RAM on wcarchive (4MB in the near future). I just went through this in email with Matt Dillon who was also adding something to vm_page. So, the bottom line is that if it results in a neutral or reduction of total memory use in the system - merging pv_entry with vm_page, for example, then I'm open to looking at it further. If not, well, you better have a REAL good reason. :-) -DG David Greenman Co-founder/Principal Architect, The FreeBSD Project To Unsubscribe: send mail to majordomo@FreeBSD.org with "unsubscribe freebsd-arch" in the body of the message
