Overstreet Date: Wed Dec 27 18:31:46 2023 -0500 bcachefs: KEY_TYPE_accounting New key type for the disk space accounting rewrite. - Holds a variable sized array of u64s (may be more than one for accounting e.g. compressed and uncompressed size, or buckets and sectors for a given data type) - Updates are deltas, not new versions of the key: this means updates to accounting can happen via the btree write buffer, which we'll be teaching to accumulate deltas.
