1) App open()s my device inode
*) dev->open() called.
2) App mmap()s some memory through the device
*) dev->mmap() called
*) I do the MMAP dance..
*) I set vma->vm_dentry=dget(file->dentry);
3) App exits
*) dev->close() called
*) vma is unregistered
Isn't that the wrong order for #3? Shouldn't the
vma's for mallocs be cleaned BEFORE dev->close() is
called?
