/*
* bcachefs on disk data structures
*
* OVERVIEW:
*
* There are three main types of on disk data structures in bcachefs (this is
* reduced from 5 in bcache)
*
* - superblock
* - journal
* - btree
*
* The btree is the primary structure; most metadata exists as keys in the
* various btrees. There are only a small number of btrees, they're not
* sharded - we have one btree for extents, another for inodes, et cetera.
