linux-pnfs pnfs-all-3.1-rc10-2011-10-18
Subsystems (2)
I rebase the pnfs tree onto v3.1-rc10 AND
merged Bruce's for-3.2 branch that includes major changes to the stateid bookkeeping infrastructure.
Layout stateids now uses the new idr (radix tree) based mechanism and therefore it's cleaner and faster.
DS stateids are still tracked in a global hash table (as they are generated by the MDS)
I also seized the opportunity to clean up the pnfs patch series. white space, use of inline, etc. no functional changes otherwise.
Tested to pass the connectathon tests over pnfsd-lexp.

By DS stateid's you're talking about stateid's that a DS receives on IO?
I hadn't thought about those....
Does the DS need to do anything with them other than look them up and make a binary OK vs. BAD_STATEID decision?

Yes, basically.
Eventually, this needs to work with the infamous back-end protocol to enforce client fencing.
