Who can manipulate the pages on the inactive page queue? How to guarantee that a page won't move from the inactive queue while paging out? (2) I find that the VM fault routine vm_fault() can call tsleep() to sleep! This contradict my knowledge that interrupt routine can never go to sleep. How can this happen? Any help is appreciated. -------------------------------------------------- | Zhihui Zhang, http://cs.binghamton.edu/~zzhang | | Dept. of Computer Science, SUNY at Binghamton | -------------------------------------------------- To Unsubscribe: send mail to majordomo@FreeBSD.org with "unsubscribe freebsd-hackers" in the body of the message
