Message-ID: MIME-Version: 1.0 Content-Type: TEXT/PLAIN; charset=US-ASCII Sender: owner-freebsd-hackers@FreeBSD.ORG Precedence: bulk X-Loop: FreeBSD.ORG Hi, friends: I am reading VM source code concerning the vm_map_entry structure. There is a flag called MAP_ENTRY_IS_A_MAP used widely, but I search all the codes in VM and can not find where this flag gets set into the eflags field of the vm_map_entry structure. By the way, MAP_ENTRY_IS_A_SUB_MAP is set in vm_map_submap( ). It is often used together with MAP_ENTRY_IS_A_MAP. I hope someone can give me a hint on this. Thanks a lot. ------------------------------------------------- Zhihui Zhang Department of Computer Science State University of New York at Binghamton Web Site: http://cs.binghamton.edu/~zzhang ------------------------------------------------- To Unsubscribe: send mail to majordomo@FreeBSD.org with "unsubscribe freebsd-hackers" in the body of the message
