Quick, possibly dumb question: I've been beating my head against these for a little bit, and I can't figure out what's supposed to happen in this case: mlock2(addr, len, MLOCK_ONFAULT); munlock2(addr, len, MLOCK_LOCKED); It looks to me like it will clear VM_LOCKED without actually unlocking any pages. Is that the intended result? Thanks, jon -- To unsubscribe, send a message with 'unsubscribe linux-mm' in the body to majordomo@xxxxxxxxx. For more info on Linux MM, see: http://www.linux-mm.org/ .
