These are the last of the on disk format changes that will be required
upgrades. Future on disk format changes will be optional - meaning
they'll require more compat code.
- metadata_version_cached_backpointers: scrub can now check cached data,
and (more importantly) the gc_gens pass for recalculating
bucket.oldest_gen is no longer required - necessary scalability item.
- metadata_version_stripe_backpointers: needed for scrub to properly
support erasure coding, and for future stripe repair code
- metadata_version_stripe_lru: we no longer have to read stripes into
memory at startup for the stripes heap, for reusing partially empty
stripes
- metadata_version_casefolding: I think this one will make some people
happy :)
Joshua, the casefolding patches needed some work to rebase, could you
look them over? Hongbo, I had to tweak your directory i_size code as
well.
