flex_array: export symbols to modules
Alex said:
I want to use flex_array to store a sparse array of ATM cell
re-assembly buffers for my ATM over Ethernet driver. Using the per-vcc
user_back structure causes problems when stacked with things like
br2684.
Add EXPORT_SYMBOL() for all publically accessible flex array functions
and move to obj-y so that modules may use this library.
