bcache: Explicitly track btree node's parent This is prep work for the reworked btree insertion code. The way we set b->parent is ugly and hacky... the problem is, when btree_split() or garbage collection splits or rewrites a btree node, the parent changes for all its (potentially already cached) children. I may change this later and add some code to look through the btree node cache and find all our cached child nodes and change the parent pointer then...
