>  - fix for a nasty extents + snapshot interaction, reported when reflink
>    of a snapshotted file wouldn't complete but turned out to be a more
>    general bug
>  - fix for an invalid free in dio write path when iov vector was longer

>  - fix for a buffer overflow in the nocow write path - BCH_REPLICAS_MAX
>    doesn't actually limit the number of pointers in an extent when
>    cached pointers are included
>  - RO snapshots are actually RO now
>  - And, a new superblock section to avoid future breakage when the disk
>    space acounting rewrite rolls out: the new superblock section
>    describes versions that need work to downgrade, where the work
>    required is a list of recovery passes and errors to silently fix.
