(1) Can anybody tell me the different usages of those copy-on-write flags: MAP_COPY_NEEDED (MAP_ENTRY_COPY_NEEDED), MAP_COPY_ON_WRITE (MAP_ENTRY_COW), and MAP_NOFAULT (MAN_ENTRY_NOFAULT)? (2) I guess the field is_main_map is never used (just like shared map). Is that correct? 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
