bcachefs: bcachefs_metadata_version_stripe_lru
Add a persistent LRU for stripes, ordered by "number of empty blocks", i.e. order in which we wish to reuse them. This will replace the in-memory stripes heap, so we can kill off reading stripes into memory at startup. Signed-off-by: Kent Overstreet <kent.overstreet@linux.dev>
