The special check feels a bit odd for me, given that 1. It's hard to imagine anything that would not be "special", and still would implement vma_close(). I presume that something like this exists. Just cannot make up anything. 2. On the other hand, is_mergeable_vma() pretty much sets the constraints to merge to VMA's into one. Most importantly it checks that vm_close() is not implemented and VMA's map the same file. BR, Jarkko
