Hi there everybody! Ok, here's my problem (character device driver)
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?
