Does pageproc stand for the pageout daemon? (2) It seems that pageout daemon can sleep on either vm_pages_needed or vm_pageout_pages_needed. When does pageout deamon itself need pages? (3) Can pageout daemon be waken up at interrupt time? If not, why we check this at the beginning of vm_page_alloc()? 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
