Just wondering, but was CEPH_FEATURE_FS_FILE_LAYOUT_V2 supposed to have
exactly the same value as CEPH_FEATURE_NEW_OSDOPREPLY_ENCODING (and
CEPH_FEATURE_CRUSH_TUNABLES5)??
Because when I backported this patch (and many others) to some ancient
enterprise kernel, it caused mounts to fail.  If it really is meant to
be the same value, then I must have some other backported issue to find
and fix.

Thanks,
NeilBrown
