It's tripped a radix-tree internal bug when setting a tag on the tree
indicating that the index is not actually in the tree. Which, AFAICT, shouldn't
be possible. There's two possible radix trees that are tagged in this function, 

How reproducable is it? If you can reproduce it, getting a trace of the
xfs_destroy_inode, xfs_perag_get, xfs_perag_set_reclaim and xfs_iget* trace
points might help show what inode or AG index it was that died and whether it
is actually in the radix tree or not...

Dave.
