This was more for developing. I added that to be really sure those
requirements are met. As I said, the amount of assertions will be
lessened and these ones will be deleted. There are other assertions
in the VFS calls implementation functions, which also will be deleted.

I'll look at the SLUB.

You still do not explain what is wrong with this. For me it means that
ubifs_setattr() was called for inode 65. And when I debugging a bug I
know what's going on.

Fair enough. As I said, we will review debugging and lessen the amount of
it.

Thanks.
