Description
because osd-zfs doesn't maintain cache hit/miss stats, there is just no regular API for this at the moment.
adilger I checked ZFS sources and it looks that there is no easy way to get stats for Lustre-related dbufs - all stats ZFS collects are global. We could pre-lookup dbufs and check its status, but that would be +1 lookup for every dbuf which isn't free. not sure we want to pay that price.
