Good to see it working... you had me scratching my head a bit there...

I assume you see these in the trace during yaffs_clear_inode() or similar. For

don't cater properly for some corner conditions on zombied objects (eg.
checking for a sane well connected object that has been partially deleted).
Something I should clean up...
