Hi Tom


this is a change to 2.6.18.3 version only - and it is in place of code that
sync's the # of session slots to the number of rpc_slots. currently, the #
of session slots is bound at compile time to the default # of rpc_slots.

we are freezing features on 2.6.18.3, and using this version for performance
tesing/demonstrations until the linux-pnfs-2.6.-latest kernel is ready.

-->Andy
