The effect of this was that removal of a shared block\ncould result in the space maps thinking the block was no longer used.\nMore concretely, if you have a thin device and a snapshot of it, sending\na discard to a shared region of the thin could corrupt the snapshot.\n\nThinp uses a 2-level nested btree to store it\u0027s mappings. This first\nlevel is indexed by thin device, and the second level by logical\nblock.\n\nOften when we\u0027re removing an entry in this mapping tree we need to\nrebalance nodes, which can involve shadowing them, possibly creating a\ncopy if the block is shared. If we do create a copy then children of\nthat node need to have their reference counts incremented. In this\nway reference counts percolate down the tree as shared trees diverge.\n\nThe rebalance functions were incrementing the children at the\nappropriate time, but they were always assuming the children were\ninternal nodes.
