Joel, but please, send small patches, preparation patches, etc. Do not
disappear for several months and do not come back with another big
patch. Tell about your intentions in advance.

E.g., if you decide to start using those unused 8 bytes - first do small
preparations like removing the notion of "key scheme" which we
provisioned but never used (from comments as well). Clean-up the "space"
for yourself. Then start using them for your purposes. As I said, as
soon as I get the first patch I like, I'll create a separate branch in
the UBIFS git tree for your work.

Thanks!
