Hi, I read in the mailing list archive something like "Also the VM tends to not consult the underlying object for a number of cases, the worst one being that if a write fault occurs on a read-only page, the VM will tend to add write access without asking the VFS if that is ok". Can anyone explain for me the situation and whether it has been fixed or not? 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
