--- Comment #3 from Theodore Tso <tytso@....edu> ---
If Ceph is using xattrs that are all different for each inode, the mbcache is
not really useful at all.   So I wonder if we should have a mount option which
disables the mbcache.   This will prove the scalability of the xattr functions,
and should be a pretty big performance win for Ceph.
