Well, I doubt it would be useful if someone renamed for example "xfs.ko"
to "a_btree_based_journaled_filesystem.ko" --- and it would be less
descriptive too because there are several other btree-based journaled
filesystems.
Currently, there are two exception stores for these shared snapshots, they
both use btrees and they have different format which has different pros
and cons --- so I named them according to their designers, "mikulas" and
"fujita-daniel". With what other names they should be differentiated?
