See mlock2();
SYSCALL_DEFINE3(mlock2, unsigned long, start, size_t, len, int, flags)
{
vm_flags_t vm_flags = VM_LOCKED;
if (flags & ~MLOCK_ONFAULT)
return -EINVAL;
if (flags & MLOCK_ONFAULT)
vm_flags |= VM_LOCKONFAULT;
return do_mlock(start, len, vm_flags);
}
VM_LOCKONFAULT always as VM_LOCKED set as well.
OK cool, that makes sense.
As with much kernel stuff, I knew this in the past. Then I forgot. Then I knew
again, then... :P if only somebody would write it down in a book...
And if there would be such a book in the makings, I would consider
hurrying up and preordering it ;)
