This series fixes two long standing bugs related to block removal code
of nilfs2 btree.
The first patch fixes potential filesystem corruption after having
deleted block. This may be a root cause of checkpoint file corruption
after garbage collection.
Another is a leak bug which doesn't terminate btree node block address
properly when shrinking a btree into a childless root node. This one
is harmless except it chips away free disk space in the long run.
I'll send them upstream, and forward to stable if needed.
Thanks,
Ryusuke Konishi
