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
