hmm I noticed a superflous change I did, in unmap_fixup the 'area' isn't
visible to the readers (it was just out of the tree), so we can fixup
outside the spinlock, we need to spinlock only before making it visible
again:
if (end == area->vm_end) {
lock_vma_mappings(area);
spin_lock(&mm->page_table_lock);
area->vm_end = addr;
so in short I can put the area->vm_end = addr back before the
lock_vma...
